I started by making my own tortillas with flour, salt, baking powder, oil, and water.
While letting the dough rest, I cut up about half of a large sweet potato into chunks and put it on the stove to boil.
After finishing the tortillas, I chopped up an onion and some garlic and commenced to saute them, caramelizing the onions just a little. To the onions and garlic I added some cooked kidney-bean-like beans that I had stored in the freezer for just such an occasion. I added a little more oil and quite a bit of water, as well as some salt, cumin, and chili powder.
Meanwhile, the potatoes had cooked through, so I drained and mashed them.
I also mashed the beans with the onions and garlic. Then I shredded some cheese and proceded to assemble the burritos.
On each tortilla I put some mashed sweet potato, some of the bean mixture, and some shredded cheese. Then I wrapped it all up and placed the burritos in a pan to bake in the oven for a few minutes.
While they were baking, I chopped up another onion, some garlic, a pepper, and a bunch of little tomatoes to make a salsa.
Over all, I would say they turned out quite well and I would make them again.
