Preheat your oven to 425°F (220°C). In a mixing bowl, combine the diced red bell pepper, sliced carrots, diced red onion, and zucchini. Drizzle with 2 tablespoons of olive oil, sprinkle with salt, and toss until everything is well-coated.
Spread the seasoned vegetables evenly on a large baking sheet. Roast in the preheated oven for 20-25 minutes, or until the vegetables are tender and slightly caramelized. Stir halfway through for even roasting.
In a medium saucepan, combine the low-sodium chicken broth, turmeric, and remaining 2 tablespoons of olive oil. Bring the mixture to a boil over medium-high heat. Remove from heat and stir in the dry couscous. Cover and let it sit for about 5 minutes to absorb the broth.
Remove the lid and fluff the couscous with a fork. Stir in the minced garlic, ground cumin, ground coriander, and ground cinnamon. Mix well to combine all the flavors.
In a large bowl, combine the fluffed couscous, drained chickpeas, roasted vegetables, and raisins. Drizzle with fresh lemon juice, and gently fold everything together until evenly mixed.
Sprinkle the toasted slivered almonds, minced cilantro, and mint over the top. Serve warm and enjoy the vibrant flavors.
