Preheat your oven to 400°F and line a large baking sheet with parchment paper.
In a large bowl, combine the chickpeas, diced red bell pepper, and sliced zucchini.
Drizzle with olive oil and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper, tossing well to coat.
Spread the vegetables and chickpeas in a single layer on the prepared baking sheet.
Roast for 20 to 25 minutes, or until the vegetables are tender and the chickpeas have reached a light, golden crispness.
While roasting, whisk together the Greek yogurt and lemon juice in a small bowl until the consistency is smooth.
Portion the roasted mixture into serving bowls and top with a generous dollop of the lemon-yogurt sauce.
Garnish with crumbled feta cheese and pepitas before serving warm.
