Take two non-fat wheat flour tortillas.  Spread them thinly with hummus (I like roasted red pepper) or any kind of mashed beans.  Sprinkle grated cheese all over (but not too much or it will be hard to roll). I use reduced-fat cheddar mixed with some fresh parmesan.  Any cheese should work.  Take a few spoonfuls of roasted/cooked vegys and spread that over thinly.  This is where I stop but you can add any meats or cheeses.

Starting from one side, roll them very tightly and lay them down so the side that is folded over is underneath.  These are DELICIOUS and would probably make good hors d'ouvres if you sliced them up.  Best of all, they are healthy and low-fat.
