Preheat your oven to 375°F and line a baking sheet with parchment paper. Meanwhile, cook the ground beef in a skillet over medium heat until fully browned, then drain excess fat.
Add onions, bell peppers, garlic powder, salt, and pepper to the beef, cooking for another 3 minutes until softened. Stir in ketchup and mustard, then remove from heat.
Roll out the pizza dough into a large rectangle on a lightly floured surface. Make sure it is even to ensure proper baking.
Spread the beef mixture evenly over the dough, leaving a small border around the edges. Sprinkle bacon, cheddar, and mozzarella on top.
Carefully roll the dough into a tight log, sealing the edges and placing it seam-side down on the baking sheet. Brush the top with beaten egg.
Bake Garbage Bread for 25–30 minutes until golden brown. Let it cool slightly before slicing and serving warm.
Pro Tips for the Best Garbage Bread
Chill the filling for 10 minutes before assembling to prevent soggy dough and improve structure.
Add a thin layer of shredded cheese directly on the dough first to act as a moisture barrier.
Use a serrated knife for slicing to maintain clean cuts without crushing the loaf.
Let the bread rest at least 5 minutes after baking so the filling sets perfectly.
