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 soggy filling.

Add Worcestershire sauce, beef bouillon powder, onion powder, garlic powder, salt, and black pepper to the skillet. Stir well to combine. Pour in tomato sauce, ketchup, mustard, and brown sugar, mixing thoroughly. Adjust seasoning to taste. Allow the filling to cool until warm but not hot to avoid melting dough.

Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper or a light coat of oil. Unroll pizza dough and gently stretch into a rectangle. Sprinkle half of the shredded Colby cheese evenly over the dough, leaving a border around edges. Spread the cooled sloppy joe filling evenly on top, then layer with remaining cheese.

Fold dough edges toward the center, slightly overlapping, and pinch or fold ends under to seal sides firmly. Press edges to close completely. Use a sharp knife to cut 4 or 5 slits on top for steam release. Brush entire surface with melted butter for shine and enhanced browning.

Bake in the preheated oven for 15 to 20 minutes until the crust is deep golden and sounds hollow when tapped. Remove from oven, allow to cool slightly before slicing into generous portions, and serve warm.
