Instructions: 1) Preheat oven to 250 degrees. If using taco shells, separate and place on baking sheet. If using tortillas, wrap in foil. Bake taco shells or tortillas until heated through, about 10 minutes. Or, wrap tortillas in damp paper towels and heat in a microwave oven on high (100 percent power) for 30 to 60 seconds.

2. Meanwhile, in large nonstick skillet, combine beans, garlic, onion, chilies, tomato paste and red pepper flakes. Bring to a simmer, stirring constantly. Cover and cook over low heat 10 minutes, adding small amounts of water if necessary to prevent sticking. Uncover and, if any juices are left, increase heat and cook until most of the liquid evaporates. Mash beans down to a chunky texture with a fork.

3. To assemble, in each taco shell or tortilla spoon 2 heaping tablespoons filling. Top with cheese, lettuce and tomato. Roll tortilla around filling ingredients.
