Preheat your oven to 400°F (200°C).
In a large bowl, combine the chickpeas, cauliflower florets, olive oil, chili powder, cumin, garlic powder, onion powder, salt, and pepper. Toss until everything is well coated.
Spread the chickpea and cauliflower mixture on a baking sheet in a single layer. Roast in the preheated oven for 25-30 minutes, or until the cauliflower is tender and slightly crispy. Stir halfway through for even cooking.
Remove from the oven and drizzle with lime juice. Toss gently to combine.
To assemble the wraps, place a generous amount of the roasted chickpea and cauliflower mixture onto each tortilla. Top with shredded lettuce, diced tomatoes, avocado slices, and fresh cilantro.
Roll up the tortillas tightly, folding in the sides as you go. Cut in half if desired and serve immediately.
