My family loves taco's and they love pizza. So whats a better way to get both, to make a taco pizza. Out of one pan I had 2 slices left.

1 lbs hamburger, browned and drained
1 package taco seasoning
1 med onion, dices
2 tomato's, diced
2 1/2 cups cheeder cheese
1 tube pizza dough
1 can sliced olived
1 can refried beans
lettuce

Heat oven to pizza dough directions.
After you brown and drain the hamburger, add the taco seasoning and water according to the package; cook down.
After you spread out the pizza dough, top with refried beans, then the hamburger, top with cheese, olives, tomato's, onion and lettuce. Cook according to pizza package, add up tp 5 mins more if dough not done in the center. After it is done cooking, top with salsa and sour cream.
