Prep the fillings and preheat a grill pan or skillet to medium high.
Spread each tortilla with one binding ingredient - mashed sweet potato, refried beans, mashed avocado or cheese - so that your quesadillas will stick together.
Add desired veggie fillings. Fold each tortilla in half over the fillings and gently press down.
Cook each quesadilla for 2 to 3 minutes per side, until light char marks form. Remove from the pan, slice into wedges and serve.
Notes
*To make these gluten free you can use corn tortillas - although I prefer wheat tortillas for quesadillas (I like Whole Foods' brand) because they are easier to handle and less likely to break.
