Let pizza dough rest at room temperature for about 20 minutes.

While dough is resting, brown beef in a large skillet. Add the taco seasoning, add water called for on the package, and cook according to the package instructions. Set aside.

Preheat oven to 400 degrees. Press or roll the dough onto a 12-inch pizza pan, pizza stone, or larger pan.

Bake for 8 minutes. Remove from oven.

In a small bowl, stir together the refried beans and salsa. Spread a thin layer onto the pizza crust.

Sprinkle with the ground beef mixture, cheese, and olives. Bake for about 5 minutes or until cheese is completely melted. Remove from the oven and top with tomatoes and green onions. You can add a dollop of sour cream to the center or let everyone top their own. Add taco sauce if desired.
