Brown ground beef, drain. Add taco seasoning according to directions. Add ranch style beans and 1 can water. Stir. Lower heat to medium.
Add flour tortillas, torn into bite-sized pieces. Stir to make sure all tortillas are moist and covered (mostly). Lower heat to low and simmer uncovered, about 10 minutes or until water is mostly absorbed.
Turn off heat and cover with shredded cheese. Let sit for 2-3 minutes or until cheese is melted.
