In a large skillet, cook the beef, bacon and onion over medium heat until browned; drain. Add cheese, cook and stir over low heat until melted. Set aside.
Roll out pizza dough (sprinkle flour on the counter before rolling if you need to use a rolling pin). Cut dough into four-six individual portions. Make sure that each portion of dough is flat (they can be round or square – it doesn’t matter). I like to use a small round bowl (flipped upside down) to trace and cut out the dough.
Spoon beef mixture onto center of each piece of dough (leave a border). Moisten the edges with a small amount of water (this will help the dough seal shut), and fold dough over filling to close. Pinch the edges of each circle to seal closed. Place on a greased baking sheet and brush with olive oil. Depending on how full you stuff your pockets, you might have some leftover beef mixture. Refrigerate the leftovers and use the meat as a stuffing for baked potatoes, as a filling for sandwich rolls, tossed with mac and cheese, or wrapped in tortillas.
Bake at 400F (200C) for 15-20 minutes or until golden brown. Serve with ketchup and mustard for dipping.
