11.In a large skillet, sauté onion and garlic until soft (I actually leave my onion a bit crunchy).
2.In a separate pot, heat black beans and corn until warm.
3.After onions are at desired texture, add mashed yams/sweet potatoes to skillet (Since canned yams are very soft I mash mine in the skillet).
4.After yams are warm, spoon the black bean/corn mixture into the skillet leaving the bean juice behind. Mix and heat.
5.In a small dish mix mustard, soy sauce, cumin, chili powder, turmeric, and cayenne pepper. Add to skillet.
6.If the mixture seems paste-like, add a small amount of water until a desired consistency is reached.
7.Spoon onto tortilla and fold into a burrito. Enjoy!
