Step 1: With your hands mix together ground beef, taco seasoning and water. In a large skillet brown ground beef over medium heat for 5-6 minutes. Break up the beef up into small pieces with a spatula while cooking. Set aside.
Step 2: Add oil to a medium frying pan. Heat to medium-high and fry tortillas one by one for 30 seconds (or until browned) on each side. Be sure to pop any bubbles that form while cooking. You want to keep the tortillas as flat as possible. Remove from pan and drain on paper towels.
Step 3: Warm refried beans and pre-heat the oven to 400 degrees. Stack each pizza by first spreading a layer of refried beans, then a layer of meat followed by a layer of salsa. Now stack another tortilla on top. Stack cheese on top of that followed by tomatoes and green onions. Repeat until all pizzas are stacked.
Step 4: Place on a baking sheet and put into the oven. Bake on 400 degrees for 8 minutes.
