Prepare the Beef Mixture:

1. Cook the Ground Beef:

   • In a large skillet, cook the ground beef over medium heat, breaking it apart with a spatula, until browned and fully cooked (about 5-7 minutes).

2. Season the Beef:

   • Add the taco seasoning and water to the beef. Stir to combine and simmer for 5 minutes until the mixture thickens. Remove from heat and set aside.

Assemble the Mexican Pizzas:

1. Preheat the Oven:

   • Preheat your oven to 375°F (190°C).

2. Toast the Tortillas:

   • Lightly toast the flour tortillas in a dry skillet over medium heat for 1-2 minutes on each side, or bake in the oven for a crispier texture.

3. Spread Refried Beans:

   • Lay each toasted tortilla on a baking sheet. Spread a thin layer of refried beans on each tortilla.

4. Add the Beef Mixture:

   • Spoon the beef mixture over the beans and spread it evenly.

5. Top with Enchilada Sauce and Cheese:

   • Pour enchilada sauce over the beef mixture and sprinkle both shredded cheddar and pepper-jack cheese over each pizza.

Bake the Pizzas:

1. Bake the Mexican Pizzas:

   • Place the pizzas in the oven and bake for 10-12 minutes, or until the cheese is melted and bubbly and the edges of the tortillas are crispy.

2. Remove from Oven:

   • Once baked, remove from the oven and set aside.

Add Fresh Toppings:

1. Garnish the Pizzas:

   • Top each pizza with diced Roma tomato, green onions, and sliced black olives.

2. Slice and Serve:

   • Slice the pizzas into wedges and serve immediately. Add sour cream or guacamole on the side for extra flavor.
