Preheat the oven to 400°F. Grease a large baking sheet.
Roll the dough out onto the baking sheet, pressing it to the edges. Bake for 8 minutes.
Brown the ground beef in a medium skillet over medium-high heat. Drain the grease.
Stir in the taco seasoning, then stir in the refried beans.
Spread the salsa over the pizza crust, followed by the beef and bean mixture.
Sprinkle cheese over the entire pizza, then top with olives.
Bake for an additional 8–10 minutes, until the cheese is melted and bubbly.
While the pizza bakes, dice the tomato and slice the green onions.
Once the pizza is out of the oven, sprinkle the tomato and onions over the top, and slice.
Serve with sour cream on top of the slices.
