This sounds like the bean base for a taco pizza. Not sure how wide spread it is, but where i am from in the Midwest it is pretty popular. Pizza Hut has a Taco Bean and a Taco Beef Pizza. Add cheddar cheese, pop it in the oven, after it's done baking, add lettuce, more cheddar cheese, tomatoes, chushed up Doritos, and some sour cream. So good.
