Preheat the oven to 400°F.
In a large bowl, combine the zucchini, bell peppers, red onion, and cherry tomatoes. Drizzle with olive oil and sprinkle with garlic powder, dried oregano, salt, and pepper. Toss until the vegetables are evenly coated.
Spread the vegetables in a single layer on a baking sheet. Roast in the preheated oven for 20-25 minutes, or until tender and slightly caramelized, stirring halfway through.
While the veggies are roasting, prepare the wraps by spreading ½ cup of hummus evenly over each tortilla.
Once the vegetables are done, remove them from the oven and let them cool for a few minutes.
Layer the roasted veggies and fresh spinach leaves on top of the hummus-covered tortillas.
Roll the tortillas tightly, tucking in the sides as you go. Slice each wrap in half and serve immediately.
