I rarely eat burritos in their proper, wrapped-up package anymore. Throwing all the components into a bowl is so much easier to eat and involves a lot less effort. Add to this my love of baked and stuffed sweet potatoes, and you have the inspiration for this dish. While the sweet potatoes roast, you have ample time to fix all the filling components: some spiced beans and rice, a rustic salsa, and guacamole.
