Heat about 1/2 inch of vegetable oil in a 10-inch skillet. Heat the oil to 350 degrees. When the oil is hot place 1 tortilla into the hot oil. Cook for about 30 to 60 seconds until the shell crisps.
When the tortilla is crispy, remove it from the oil and drain it on a wire rack.
Repeat with remaining tortillas.
Making the pizzas
Spread two tablespoons of refried beans onto six of the fried tortillas.
Sprinkle two tablespoons of seasoned and cooked ground beef over the refried beans.
Sprinkle 1 tablespoon of shredded cheese on top of the ground beef.
Add a fried tortilla to the top of the ground beef and cheese layer.
Sprinkle two tablespoons of cheese on top of the tortilla. Microwave for about 30 seconds, just until the cheese melts.
Add diced tomatoes and green onions to the top of the cheese on each of the pizzas.
