2 pounds Ground Beef
2 Cups Shredded Cheddar Cheese
All-purpose flour, for dusting
1 1/2 Pounds Store-Bought Pizza Dough, at room temperature
5 tablespoons Ketchup
2 tablespoons Yellow Mustard
1 Medium Red Onion, finely chopped
12 Strips Cooked Bacon, broken in half
Pickles, if desired
1/2 cup Mayonnaise
1 Teaspoon Dried Onion Flakes
1 Teaspoon Sugar
Salt and Pepper
Preheat the oven to 400* and line a baking sheet with parchment paper.
Heat a large skillet over medium heat.
Add the beef and cook.
Discard the fat and liquid in the pan.
Let the beef cool completely in the bowl, then stir in the chopped cheese.
On a lightly floured work surface, roll the dough into a 20-by-14-inch rectangle.
Arrange the beef and cheese mixture evenly on one half of the dough.
Drizzle 2 tablespoons ketchup evenly over the beef mixture and the uncovered half of the dough; repeat with all the mustard, and then the red onion.
Lay down the remaining cheese evenly over the half of the dough with no beef mixture, leaving a 1-inch border on the sides. Arrange the bacon pieces and pickles just over the beef mixture.
Working from the short side with the beef mixture, tightly roll up the dough into a log, jelly-roll style. Pinch the open ends together to seal, then tuck them underneath the log. Transfer the log, seam side-down, to the prepared baking sheet, brush all over with water and sprinkle with sesame seeds. Bake, rotating the pan halfway through, until the bread is golden brown, about 40 minutes.
While the bread bakes, whisk together the mayonnaise, onion flakes, sugar, a pinch of salt and pepper and the remaining 3 tablespoons ketchup, in a small bowl. Taste, and season the special sauce with additional salt if needed. Let the bread cool for 10 minutes. Slice into 8 pieces and serve warm with the special sauce.
