On a large baking sheet, combine the cubed sweet potato, chopped bell pepper, zucchini, and chickpeas. Drizzle with olive oil and sprinkle with garlic powder, smoked paprika, cumin, salt, and pepper. Toss to coat evenly.
Spread the vegetables and chickpeas out in a single layer.
Roast in the preheated oven for 20-25 minutes, or until the vegetables are tender and slightly caramelized, and the chickpeas are crispy. Toss halfway through for even roasting.
Top with the roasted vegetables and chickpeas.
Drizzle with the Maple Dijon Tahini Dressing and garnish with fresh parsley or cilantro if desired.
