how about sweet potato quesidillas (I think it's spelled wrong)?
Basically just boil and mash the sweet potatoes, then add some sauteed onion and garlic and what ever other cooked vegetables you like, I like small pieces of broccoli, corn, mushrooms. Then add a dash or chili powder and cumin and mix it all together. Spread it on a soft tortilla, put cheese on top and then another soft tortilla on top. To cook you can either bake in the oven on a cookie sheet until it browns, I like to spray a little pam on it or fry in a frying pan (I don't), or for my son I just microwave some so that it is easier to chew for him. Serve with sour cream or salsa.
We love them, and it's really hard to go wrong, pretty much put in what you like.
