Preheat your oven to 425°F (220°C).

In a skillet over medium heat, cook the ground beef or chicken until browned. Drain excess fat if necessary. Stir in the taco seasoning along with a bit of water from the package, and let it simmer for about 5 minutes until well-combined.

On a well-floured surface, roll out your pizza dough to fit your sheet pan, ensuring it’s even and reaches the edges.

If using refried beans, spread an even layer over the dough. Next, add the cooked meat mixture, spreading it out evenly.

Sprinkle shredded cheese over the meat, then add your diced tomatoes, bell peppers, olives, and jalapeños.

Place the sheet pan in the preheated oven and bake for about 15-20 minutes, or until the crust is golden brown and the cheese is bubbling.

Take it out of the oven, let it cool for a minute, and then garnish with sour cream, diced avocado, and fresh cilantro.

Slice into squares and serve warm.
