How to Make It
To prepare salsa, combine first 5 ingredients in a small bowl. Toss gently, and set aside.
Combine 2 tablespoons water, lime juice, cumin, salt, ground red pepper, and black beans in a blender; process until smooth.
Place tortillas on a baking sheet, and spread about 1/4 cup black bean mixture evenly over each tortilla. Top each evenly with 1/4 cup chicken and 3 tablespoons cheese. Broil 2 minutes or until cheese melts and tortilla edges are just beginning to brown.
Top each tortilla with 1/4 cup lettuce, 1/4 cup salsa, and 2 tablespoons sour cream. Cut each tortilla into 4 wedges.
