Preheat your oven to 400°F (200°C). Spread the drained and rinsed chickpeas on a baking sheet. Drizzle with 1 ½ tablespoons olive oil, then sprinkle with 1 tablespoon za’atar, 1 ½ teaspoons garlic powder, and a pinch of sea salt and black pepper. Toss well to coat evenly. Roast for 20-25 minutes, shaking the pan halfway through, until the chickpeas are golden and crunchy.
In a small bowl, combine ½ cup plain hummus, 2 tablespoons lemon juice, 2 tablespoons olive oil, and 1 tablespoon Dijon mustard. Season with sea salt and ground black pepper to taste. Add 2 tablespoons water to thin the dressing to a pourable consistency. Whisk until smooth and creamy.
While the chickpeas roast, chop the iceberg lettuce into bite-sized pieces. Peel and julienne or use matchstick carrots, then roughly chop the parsley leaves. Place all fresh veggies in a large mixing bowl. Season lightly with sea salt and black pepper.
Pour the hummus dressing over the chopped veggies and toss gently to coat evenly. Add the roasted za’atar chickpeas and toss carefully so they stay crunchy. Sprinkle extra za’atar over the top.
Right before serving, toss in 1-2 cups of pita chips for added crunch. Alternatively, swap pita chips for homemade croutons.
