Follow these steps to create your delicious Grilled Veggie Wraps:

1. Preheat your grill or grill pan over medium-high heat.
2. In a bowl, combine sliced zucchini, bell pepper, eggplant, and red onion. Toss with olive oil, salt, and pepper.
3. Arrange the vegetables in a single layer on the grill. Cook for about 5-7 minutes, turning occasionally until they are tender and have grill marks.
4. While the vegetables are grilling, prepare your tortillas by spreading hummus or tzatziki sauce evenly across the center of each wrap.
5. Once the vegetables are done, remove them from the grill and let them cool for a moment.
6. On top of the sauce-covered tortillas, layer a handful of fresh spinach or mixed greens.
7. Add a generous portion of the grilled vegetables on top of the greens.
8. If desired, sprinkle with feta cheese, fresh herbs, or avocado slices for added flavor.
9. Roll the wraps tightly, starting from one end and tucking in the sides as you go, to ensure nothing spills out.
10. Slice the wraps in half and serve immediately, or wrap them in foil for a delicious meal on the go.
