Preheat your oven to 425°F (220°C).
Roll out the pizza dough on a floured surface to fit the sheet pan. Transfer the dough to the sheet pan, pressing it to form an even layer.
In a large skillet over medium heat, cook the ground beef until browned, about 5-7 minutes. Drain any excess fat and stir in the taco seasoning according to package instructions. Set aside.
Spread the refried beans over the pizza dough, leaving a small border around the edges.
Pour the salsa evenly over the refried beans.
Sprinkle the cooked ground beef mixture on top of the salsa.
Evenly distribute the shredded cheddar cheese over the entire pizza.
Bake in the preheated oven for 15-20 minutes, or until the cheese is bubbly and golden brown.
Remove from the oven and let it cool slightly.
Top the pizza with shredded lettuce, diced tomatoes, black olives, sliced jalapeños, and a dollop of sour cream.
Garnish with fresh cilantro, if desired.
Slice into squares and serve warm.
