Preheat oven to 400°F. In a large saucepan or skillet over medium heat, cook ground beef until no longer pink and crumbly. Drain grease.
Increase heat to medium-high heat. Add taco seasoning and water and cook until water is evaporated making sure to stir occasionally (about 5 minutes).
In a separate large skillet, heat 1 cup vegetable oil over medium heat. Add one of the 8 flour tortillas (taco size) and cook for about 3-4 minutes (flipping frequently) until crisp. Continue with the rest of the tortillas. Set aside.
Meanwhile, heat the 15-ounce can of refried beans in a microwaveable-safe bowl. This will make it easier to spread the beans onto the tortilla shells.
On each fried tortilla, slather a generous layer of refried beans. Then top with seasoned ground beef.
Place another tortilla on top. Slather about two tablespoons from the 10-ounce can of enchilada sauce on top. Place some of the 2 cups of shredded Mexican cheese blend on top of the sauce. Continue assembling the rest of the pizzas.
Place the pizzas on a large nonstick baking sheet and bake for about 8-10 minutes or until the cheese is melted. Serve with your favorite toppings like diced tomatoes, sliced green onion, sliced olives, and sour cream.
