1 small can tomato sauce

Add all ingredients to a saucepan. Rinse each can with 1/2 can of water each and pour into pan. Mix all ingredients and simmer for 1 hour. Spoon mixture onto flour tortillas and serve with the following toppings: shredded Cheddar cheese, lettuce, tomatoes, olives, sour cream and so on.
