In a large skillet, cook ground beef and onion until evenly browned; drain. Stir in the cooked and crumbled bacon.
Spread a layer of pizza sauce on the pizza crust, then a layer of the meat mixture. Top with cheese.
Bake in preheated oven for 10-15 minutes, or until crust is golden brown and cheese is melted. Remove from oven.
Top with pickles and any additional toppings you prefer.
