Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
Step 2: Cook the Filling
Heat a skillet over medium heat.
Add the ground beef or sausage and diced onion. Cook until browned and fully cooked, breaking up the meat as it cooks.
Season with garlic powder, Italian seasoning, salt, and pepper. Drain any excess grease.
Step 3: Prepare the Dough
On a lightly floured surface, roll out the pizza dough into a large rectangle, about 12x16 inches.
Step 4: Assemble the Garbage Bread
Spread the mayonnaise, ketchup, and mustard evenly over the dough.
Layer the cooked meat mixture, shredded cheeses, bacon, and optional pickles or peppers over the dough, leaving a 1-inch border around the edges.
Step 5: Roll the Bread
Starting from one long side, carefully roll the dough into a log, sealing the edges and ends tightly to prevent leaks.
Place the roll seam-side down on the prepared baking sheet.
Step 6: Apply the Egg Wash
Brush the entire surface of the bread with the beaten egg. Sprinkle with sesame seeds, if desired.
Step 7: Bake
Bake in the preheated oven for 25-30 minutes, or until the bread is golden brown and cooked through.
Step 8: Slice and Serve
Let the Garbage Bread cool for 5-10 minutes before slicing into thick pieces. Serve warm with dipping sauces like marinara, ranch, or barbecue sauce.
