01 - Preheat oven to 425°F. Line a baking sheet with parchment paper for easy cleanup and to prevent sticking.
02 - Spread zucchini slices, bell peppers, and red onion wedges on the prepared baking sheet. Drizzle with 1 tablespoon olive oil, season generously with salt and pepper, and toss thoroughly to coat evenly.
03 - Roast vegetables for 20-25 minutes until golden edges appear and vegetables are tender. Stir halfway through cooking to ensure even browning.
04 - While vegetables roast, pat chickpeas completely dry with paper towels. Heat 1 tablespoon olive oil in a skillet over medium heat, add chickpeas, and sauté for 5-7 minutes while stirring frequently until golden and slightly crisp. Remove from heat and set aside.
05 - In a small bowl, whisk together remaining 1 tablespoon olive oil, lemon juice, minced garlic, Dijon mustard, chopped parsley, chopped mint, and a pinch of salt and pepper until emulsified.
06 - In a large serving bowl, combine roasted vegetables, sautéed chickpeas, and cherry tomatoes. Drizzle with the lemon-herb dressing and toss gently to coat without mashing the vegetables.
07 - Divide the mixture among 4 plates. Top each serving with toasted pumpkin seeds and a generous sprinkle of fresh lemon zest before serving.
