Creating Mexican Pizza is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Crust: If using a pre-made pizza crust, place it on a baking sheet. If using tortillas, place them directly on the oven rack or a baking sheet for a crispier texture.
3. Spread Refried Beans: Evenly spread a layer of refried beans over the crust or tortilla.
4. Season Beans: Sprinkle taco seasoning over the beans for added flavor.
5. Add Cheese: Sprinkle shredded cheese over the beans, covering them well.
6. Add Toppings: Distribute diced tomatoes, black olives, corn, and jalapeño slices evenly over the cheese.
7. Bake: Place the pizza in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
8. Garnish: Remove from the oven and top with chopped green onions and fresh cilantro.
9. Serve: Allow to cool for a few minutes, then slice into wedges. Serve warm with a dollop of sour cream on the side.
