Roast them in a pan with a little oil, salt, and spices until soft and slightly crispy.
In another pan, heat black beans and season with cumin, paprika, and a pinch of salt.
Warm the tortilla or wrap.
Spread the roasted sweet potatoes in the center.
Add black beans, chopped onions, tomatoes, and lettuce.
Drizzle with lime juice or a light sauce if desired.
Roll the burrito tightly, fold the ends, and serve warm.
