Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and set aside.
Warm a skillet over medium-high heat and add a little oil.
Cook the onion for 2–3 minutes until soft, then stir in the garlic for 30 seconds.
Add the ground beef. Break it up and cook until browned, about 5–7 minutes. Drain excess fat if needed.
Season the beef with salt, pepper, smoked paprika (or chili powder), Worcestershire sauce, ketchup, and mustard.
Stir in the chopped pickles. Taste and adjust seasoning. Let the mixture cool for 5 minutes.
While the beef cools, cut the cheddar into small cubes.
You’ll want one cube for each bomb bite.
Open the biscuit dough or divide the pizza dough into 16 equal pieces. Flatten each piece into a circle, about 3–4 inches wide. Keep the remaining pieces covered so they don’t dry out.
Place a spoonful of the cooled beef mixture in the center of a dough circle, add a cheese cube on top, and fold the dough up and over the filling.
Pinch the seams tightly to seal. Roll gently into a smooth ball, seam-side down.
Arrange the balls on the prepared baking sheet with space between them. Brush lightly with egg wash and sprinkle with sesame seeds if using.
Bake for 12–15 minutes, or until golden brown and puffed.
If using thicker pizza dough, you may need an extra 2–3 minutes.
Cool for 5 minutes before serving. The cheese center will be hot and melty. Serve with your favorite dipping sauces.
