Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them completely dry with a clean kitchen towel.
Press the tofu to remove excess moisture and cut it into 1/2-inch cubes.
In a large bowl, toss the chickpeas, tofu cubes, chopped zucchini, and bell peppers with olive oil, sea salt, black pepper, smoked paprika, and garlic powder.
Spread the mixture in a single layer on the prepared baking sheet.
Roast for 25-30 minutes, tossing halfway through, until the chickpeas are crunchy and the tofu is golden brown.
While the medley roasts, whisk together the Greek yogurt, lemon juice, and dried dill in a small bowl to create the herb drizzle.
Remove the tray from the oven and transfer the roasted medley to a bowl.
Drizzle with the yogurt sauce and enjoy immediately.
