Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.

Cook ground beef in a skillet over medium-high heat until no longer pink. Drain excess grease.

Add diced carrot and red bell pepper to the skillet. Cook for 5–7 minutes until softened. Stir in hamburger seasoning, Worcestershire sauce, and adjust seasoning to taste.

Roll out pizza dough into a 15×10-inch rectangle. Sprinkle a layer of shredded cheddar (save some for later) then spread the beef and vegetable mixture evenly over the dough.

Roll dough tightly jelly-roll style, starting from the long side. Pinch edges to seal, place seam-side down on the baking sheet, and sprinkle the remaining cheddar on top.

Bake for 15–18 minutes until golden brown. Sprinkle with chopped parsley, let cool slightly, then slice and serve.
