Roll out the pizza dough and place it on a baking dish or pizza stone.
Bake the pizza dough for about 5 to 7 minutes, just until it starts to get lightly golden.
In the mean time, add the olive oil to a skillet; when oil is hot add onion and garlic and saute until onion is translucent. Add ground beef to skillet and taco seasoning. Cook until beef is cooked through.
Spread the refried beans over the pizza dough, next top with the ground beef mixture; add shredded cheese. Put pizza back in the oven and bake for an additional 5 to 10 minutes or until cheese has melted and crust is golden.
Finish the pizza off with the rest of the toppings, lettuce, tomatoes, green onions and olives.
Serve with salsa and sour cream if preferred.
