Preheat smoker to 275°F.
Unroll pizza dough on cutting board. Depending on how large you will want your pizza bombs, cut into 6 to 8 equal squares. Shape squares into more circular shape.
For Pepperoni Bombs: Place 1 tablespoon of pizza sauce, 2 pepperonis, and 1 square of mozzarella cheese in the center of each dough round.
For Supreme Bombs: Place 1 tablespoon of pizza sauce, 1 salami, 1 slice of smoked sausage, diced peppers, diced mushrooms, and 1 square of mozzarella cheese in the center of each dough round.
Pull edges up and over and press them together. Use the palm of your hand to make sure the dough maintains a ball shape.
Spray a 9x13 disposable aluminum tray with cooking spray. Place the pizza bombs in the tray evenly spaced.
Whisk the melted butter, garlic, and Italian seasoning in a small bowl.
Brush the mixture onto each pizza bomb.
Smoke for 1 hour at 275°F until the bombs have nicely browned. Sprinkle shredded parmesan cheese on top of each pizza bomb and smoke for an additional 2 to 3 minutes until parmesan cheese has melted.
Serve with pizza sauce alongside.
