Sweet potato/Black bean Enchiladas

I am not sure if I got this recipe from Lisa, but it's yummy and wanted to post it.

Sauce:
1 cup water
1 T starch
1 can roasted gr chiles-I used hot, and they were spicy!!
2-4 cloves garlic
1 t cumin or chili powder

Enchilada Filling:
1st bowl:
1 can black beans
4 cloves garlic
1 fresh lime juiced

2nd Bowl:
2 Diced Cooked Sweet Potatoes
1 can mild gr chiles
1/2 t gr cumin
1/2 t chili powder
Salt & pepper to taste
2 T cilantro

Additional Ingredients:
Tortilla & Cheese

Heat the enchilada sauce in a skillet until slightly thickened & boil the sweet potatoes until soft. Put a little sauce in the bottom of pan & stuff tortillas w/ potato mixture & black bean mixture. Top the tortillas with remaining sauce & cheese (if desired). Really yummy w/ Tofutti Sour Cream & a sliced avocado!
