Ingredients

• 1/2 recipe for pickled red onions
• 1/2 recipe for balsamic vinaigrette
• 1 pound flank steak
• 1 tablespoon olive oil
• 8 cups of packed Spring Mix lettuce or desired lettuce blends
• 1 cup cherry tomatoes, cut in half
• 1 sliced cucumber
• ½ small peeled and thickly sliced watermelon

• 1/2 cup sliced green onions

• Sea salt and fresh cracked pepper to taste

Make-ahead notes

You can prepare the pickled red onions and the balsamic vinaigrette up to 3 days in advance and store them in the refrigerator. The steak can be marinated briefly or seasoned just before grilling and kept, covered, in the fridge for a few hours. Assemble the salad at the last minute to keep the greens crisp and the watermelon vibrant.

Equipment

• Grill or grill pan
• Large bowl for tossing salad
• Cutting board and sharp knife
• Measuring spoons and cups
• Mixing bowl or jar for vinaigrette

Prep: Pickled red onions and balsamic vinaigrette (half recipes)

Below are simple half-recipe versions of pickled red onions and balsamic vinaigrette to match the ingredient list. If you already have these prepared, adjust the amounts you add to the salad so the total matches what’s listed in the ingredients.

Pickled red onions (1/2 recipe)

Quick pickled red onions add brightness and a lively tang that complements the sweet watermelon and salty feta. For a half recipe, thinly slice one small red onion and combine with a warm pickling liquid made from equal parts vinegar and water, a touch of sugar, and a pinch of salt. Let them sit at room temperature until cool, then refrigerate for at least 30 minutes. These keep well for several days and only improve the salad.

Balsamic vinaigrette (1/2 recipe)

The balsamic vinaigrette is an easy emulsified dressing. Whisk together balsamic vinegar, olive oil, a bit of Dijon mustard (optional), a pinch of salt, and fresh cracked pepper. Taste and adjust to balance sweet and tangy notes. Keep chilled until ready to use.

Step-by-step directions

Follow these clear steps to build the salad, grill the steak, and plate everything beautifully. The directions keep the original order of preparation while making each action easy to follow.

1. Prep the grill and steak: Take the 1 pound flank steak out of the refrigerator about 15–20 minutes before grilling so it can come closer to room temperature. Pat it dry with paper towels. Rub the steak with 1 tablespoon olive oil, then season both sides with sea salt and fresh cracked pepper to taste. Preheat your grill or grill pan to medium-high heat so it’s hot before the steak goes on.
2. Grill the flank steak: Place the seasoned flank steak on the hot grill. Cook for approximately 4–6 minutes per side for medium-rare, depending on the thickness of the steak and the heat of your grill. Use a meat thermometer if you prefer: aim for 125–130°F for medium-rare, 135°F for medium. Avoid overcooking; flank steak is best when sliced thin and served slightly pink.
3. Rest the steak: Once the steak reaches your desired doneness, transfer it to a cutting board and tent loosely with foil. Let it rest for 5–10 minutes. Resting redistributes the juices and makes slicing neater and juicier.
4. Slice the steak: Using a sharp knife, slice the steak thinly against the grain. Cutting against the grain shortens the muscle fibers and ensures each bite is tender. Set the slices aside on a warm plate while you assemble the salad.
5. Prepare the salad base: In a large bowl, add 8 cups of packed Spring Mix lettuce or your preferred lettuce blend. Toss gently to fluff the greens and create an even bed for the toppings.
6. Add vegetables and watermelon: Distribute 1 cup cherry tomatoes (halved), 1 sliced cucumber, ½ small peeled and thickly sliced watermelon, and 2 thinly sliced radishes over the greens. The watermelon should be cut into pieces that are easy to eat with a fork but large enough to showcase its texture and sweetness on the plate.
7. Incorporate aromatics and pickled onions: Scatter 1/2 cup sliced green onions across the salad. Add the 1/2 recipe of pickled red onions, arranging them so their bright color and tangy flavor are evenly distributed. If your pickled onions were made in advance, give them a quick drain so they don’t overly wet the greens.
8. Dress the salad: Drizzle the 1/2 recipe of balsamic vinaigrette over the assembled salad. Start with a modest amount and toss gently to coat the leaves and toppings evenly. You can always add more dressing to taste, but you want to avoid overdressing so the watermelon and feta shine through.
9. Add feta and season: Sprinkle 1/2 cup of Feta cheese over the tossed salad. Finish with a few pinches of sea salt and a crack or two of fresh black pepper to taste. The salty feta will balance the sweetness of the watermelon and the acidity of the vinaigrette.
10. Top with grilled steak and serve: Arrange the thinly sliced grilled flank steak over the dressed salad. Position the steak slices so they rest gently on the watermelon and greens. Serve immediately so the steak remains warm and the lettuce stays crisp.

Troubleshooting and tips

• To prevent a soggy salad, keep the dressing on the side if you expect leftovers. Dress individual portions when serving.
• If your watermelon yields extra juice while slicing, blot the wedges lightly with a paper towel before adding them to the salad.
• For added texture, sprinkle toasted nuts like sliced almonds or chopped pistachios (about 1/4 cup) on top at the end. This is optional but a lovely crunchy contrast.
• If you prefer a stronger char on the steak, increase the grill heat briefly and watch carefully to avoid burning; the goal is flavor without overcooking the inside.
• When slicing the steak, use long, confident strokes and a sharp knife to keep the slices neat.

Serving suggestions

This Watermelon Feta Salad Recipe with Grilled Steak is excellent on its own as a complete meal. Pair it with crusty bread or grilled pita for a more filling spread. A chilled white wine or a light, citrusy iced tea complements the bright flavors beautifully. For a family-style presentation, place the salad bowl in the center of the table and offer extra vinaigrette on the side for anyone who wants a little more.

Leftovers and storage

If you have leftovers, store the steak and the dressed salad separately. Keep the grilled steak in an airtight container in the refrigerator for up to 3 days. Greens dressed with vinaigrette will wilt after several hours, so it’s best to store any unused lettuce and toppings separately and reassemble before serving.
