Heat oven to 425°F. Peel and dice the sweet potato and microwave in a covered bowl 6-8 minutes until soft.
Mash with the drained black beans, taco seasoning, lime juice and a pinch of salt.
Warm the tortillas in a damp towel in the microwave for 45 seconds so they don't crack.
Spread 2 tbsp filling along one edge of each tortilla, roll tightly, and set seam-side down on an oiled sheet pan. Brush the tops with oil.
Bake 15-18 minutes until crisp. Serve with guacamole and salsa for dipping.
Freeze extra baked taquitos and reheat at 400°F for 12 minutes.
