Chop your tomatoes and lettuce and place them in separate bowls. Warm the beans and keep covered.
Cook your tortillas. Don't forget to cover your tortillas up as you go, or they will dry up. You want a soft and warm tortilla for serving.
Fill the tortillas with sliced chicken,cooked beans, tomatoes, and lettuce in the tortilla. Sprinkle your crumbled bacon on top then drizzle the ranch dressing over the contents of the taco.
Notes
These are great with guacamole, too! Spread a thick layer on the open tortillas before filling with the rest of the ingredients!
