1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Cook the Meat: In a large skillet over medium heat, cook the ground beef until browned. Drain any excess fat.
3. Add Seasoning: Stir in the taco seasoning mix along with water according to package instructions. Let it simmer for a few minutes until thickened.
4. Prepare the Crust: Roll out or place your pre-made pizza crust onto a baking sheet or pizza stone.
5. Spread Refried Beans: Evenly spread a layer of refried beans across the crust.
6. Layer the Beef: Spoon the seasoned ground beef over the refried beans, spreading it evenly.
7. Add Vegetables: Top with diced tomatoes, corn, red onion, and bell pepper, distributing them uniformly.
8. Add Cheese: Sprinkle the shredded cheese generously over all the toppings.
9. Bake the Pizza: Place the pizza in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly, and the edges of the crust are golden brown.
10. Garnish: Remove the pizza from the oven and let it cool for a minute. Garnish with fresh cilantro and sliced jalapeños if desired.
11. Slice and Serve: Cut the pizza into slices and serve hot with sour cream and salsa on the side.
