1In a large skillet over medium heat, cook the beef, onions, and bell pepper until meat crumbles and no pink remains. Drain well and return to skillet to heat.
2Add tomato sauce, ketchup, Worcestershire sauce, mustard, brown sugar, Creole seasoning, garlic powder, red pepper, and black pepper. Stir well to combine and reduce heat to low to simmer for 20 minutes, stirring frequently.
3Preheat oven to 425 degrees and spray a 13x9 pan with cooking spray. Press one can of the crescent roll dough into the prepared pan, pressing with your fingers to cover the bottom of the pan. Spoon the sloppy joe mixture on top of the dough and sprinkle evenly with the cheese. Carefully place the second sheet of crescent roll dough on top of the cheese, lightly pressing the seams together and pulling the dough out to the edges of the pan. Brush the top of the dough with milk and sprinkle with sesame seeds.
4Bake, uncovered, for 13-15 minutes until nicely golden brown. Serve immediately.
