Preheat oven on broiler setting.

In a skillet over medium heat, brown ground beef. Strain to remove any pan drippings. Return to pan and add taco seasoning and water. Reduce heat and simmer 10 minutes.

Meanwhile, heat your refried beans until they are warmed through. Also, in a separate pot heat your tomato sauce until it is warmed through.

Heat oil over medium-high heat. Fry one tortilla at a time until all are golden brown. About 2 minutes per-side.

Once the meat is brown, the beans and tomato sauce are warmed and the tortillas are fried, you can start assembling your pizzas. Starting with one crispy tortilla, layer refried beans and seasoned ground beef, then place another crispy tortilla on top. Next, spoon about 2 tablespoons of the Mexican tomato sauce on top, spreading it around with the back of your spoon. Sprinkle with cheddar and jack cheeses, diced tomatoes and green onions. Repeat until you've made four pizzas.Lay assembled pizzas on a cookie sheet, depending on the size of your cookie sheet you may need to do these in batches. Cook the pizzas under the broiler until the cheese melts, about 2 minutes.
