Preheat the oven to 350 F. In a large skillet, cook the meat with the onions, bell peppers, and garlic over medium-high heat, until no pink is left on the meat.

Add the drained diced tomatoes, Worcestershire sauce, Dijon mustard, salt, and pepper to taste. Cook until almost no liquid is left on the pan, about 5 mins.

Slice the Hawaiian buns in half without separating them and place the bottoms in a greased 9 x 13-inch baking dish. Sprinkle 1 cup of cheddar cheese on top and bake for 5 minutes until melted.

Remove the baking dish from the oven and spoon the meat mixture over the melted cheese.

Sprinkle the remaining cup of cheese over the meat.

Top each bun with ½ slice of cooked bacon and place the tops of the buns back on.

To make the glaze, place the butter, brown sugar, Worcestershire sauce, and Dijon mustard in a microwave-safe dish. Microwave until melted.

Drizzle the sauce over the buns.

Sprinkle with sesame seeds and bake uncovered, for 25 mins.
