Rinse all of the vegetables and cut off cores and ends to the veggies. Slice all of the vegetables to about 1/4 inch thick so the vegetables can lay flat on the grill. Once the vegetables are all cut thin, drizzle with 3 Tbs. melted butter (or olive oil). Season the vegetables and toss to coat.
Turn the grill to medium-high heat and then place the sliced vegetables onto the hot grill. Grill on both sides until tender and lightly golden brown grill lines. Once the vegetables are finished being grilled remove from the grill and let cool on a plate or pan.
Heat a flat griddle to medium heat. Place several tortillas on the griddle. Spread on each tortilla a generous amount of hummus. Place the shredded or sliced mozzarella cheese on top of the hummus. Add slices of your favorite vegetables and cook until the cheese is melted. Serve warm.
