Prepare taco meat per package directions.
Warm refried beans.
In a small bowl, combine enchilada sauce with diced tomatoes and green chiles.
Prepare a small amount of oil in pan to 375°F (do not put so much that it will cover the flour tortillas). Cook flour tortillas in oil for 30-45 seconds or until just golden brown, flipping once. Drain on paper towels.
To assemble: top 4 tortillas with a thin layer of refried beans, followed by a layer of taco meat. Put another tortilla on top of the taco meat. Add red sauce on top of the tortilla, followed by the Mexican cheese blend and then top with diced tomatoes and green onions if desired.
Put finished Mexican pizzas on cookie sheet and broil in oven until cheese is melted.
Cut into fourths and serve.
