Creating this Mexican Pizza is straightforward. Follow these steps for a delicious outcome:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Ground Beef: In a skillet over medium heat, brown the ground beef until fully cooked. Drain excess fat.
3. Add Seasoning: Stir in the taco seasoning and a bit of water according to the packet instructions. Mix well and let simmer for a few minutes.
4. Fry the Tortillas: In another skillet, heat a few tablespoons of olive oil. Fry each tortilla for about 1-2 minutes on each side until crispy. Drain on paper towels.
5. Layer the Ingredients: On a baking sheet, place one fried tortilla. Spread a layer of refried beans followed by a layer of seasoned ground beef.
6. Add Cheese: Sprinkle about half a cup of shredded mozzarella cheese on top of the beef.
7. Repeat Layers: Add another tortilla and repeat the layering process until you have three layers of tortillas.
8. Top It Off: Finish with a final layer of cheese and any remaining toppings, such as diced tomatoes and olives.
9. Bake: Place the baking sheet in the preheated oven and bake for 10-15 minutes, or until the cheese is melted and bubbly.
10. Garnish: Once out of the oven, let the pizza cool for a few minutes. Top with chopped green onions and shredded lettuce.
11. Serve: Cut into wedges and serve with sour cream and salsa on the side.
