I use sweet potatoes often. I bake them and top them with brown sugar and butter. I make oven baked fries with them by slicing them and then tossing them with olive oil, salt, brown sugar, cinnamon and chili powder. I sometimes mix a regular potato in there, too. I also use them in black bean and sweet potato chili as well as a soup that also has carrot, apple and lentils. I also have a vegan cookbook that has an awesome recipe for sweet potato biscuits which I make when we have veggie potpie stew.
