Preheat the oven to 500°F (260°C) with a pizza stone inside for at least 30 minutes.
Cook the beef: In a skillet over medium heat, cook ground beef until browned. Drain excess fat, stir in taco seasoning, and cook according to package instructions.
Prepare the dough: On a floured surface, roll out the pizza dough into a 12-inch circle.
Assemble the pizza: Transfer dough to a pizza peel or baking sheet. Brush with olive oil, then spread refried beans evenly over the surface.
Add toppings: Layer on taco-seasoned beef, mozzarella, and cheddar cheeses.
Bake for 10-12 minutes until the crust is golden brown and cheese is bubbling.
Finish: Remove from oven and top with diced tomatoes, green onions, cilantro, and a drizzle of salsa or taco sauce.
Slice and serve immediately for the ultimate taco-pizza experience.
Notes
Swap ground beef for shredded chicken or plant-based crumbles for a vegetarian version.
Add sliced jalapeños for extra heat.
Use homemade pizza dough for the best flavor and texture.
