In a large skillet over medium heat, cook diced onion and ground beef, stirring frequently and breaking up meat, until no longer pink, about 7 to 10 minutes. Drain excess fat to prevent sogginess.

Add Worcestershire sauce, beef bouillon powder, onion powder, garlic powder, salt, and pepper to the skillet. Stir to combine evenly. Incorporate tomato sauce, ketchup, mustard, and brown sugar. Mix thoroughly and adjust seasoning to taste. Allow filling to cool until just warm to avoid melting the dough.

Preheat oven to 425°F (218°C). Line a baking sheet with parchment paper or lightly oil. Unroll pizza dough and gently stretch into an even rectangle. Sprinkle half of the shredded cheese evenly over dough, leaving a border for sealing.

Spread the cooled beef filling evenly over the cheese layer. Top with remaining cheese. Fold dough edges towards the center, slightly overlapping, pinching ends or folding under to seal sides firmly. Cut 4 to 5 slits on top to vent steam. Brush entire surface with melted butter for browning and flavor.

Bake on middle oven rack for 15 to 20 minutes until crust is deep golden and sounds hollow when tapped. Cool slightly before slicing into portions. Serve warm.
