Black Bean and Corn Soft Tacos

Combine the sour cream and green chiles in a small bowl and set aside. Drain the beans, rinse under cold water, and place in a small saucepan. Add the corn and its liquid and cook over medium-low heat, stirring occasionally, for 8 to 10 minutes, or until hot. Drain the liquid and stir in the chili powder. Place 4 corn tortillas or 2 flour tortillas on a plate. If you are using corn tortillas, double them up, so you have 2 stacks of 2 tortillas each. Spoon some of the black bean mixture onto the centers. Top with the lettuce, cheese, and sour cream sauce as desired. Repeat with the remaining ingredients.
