Preheat oven to 400 degrees.
Heat the vegetable oil in a large skillet over medium high heat. Then add the ground beef and brown the beef.
Add the green pepper and onion to the skillet and sauté for 4-5 minutes until they are tender.
Next add in the Worcestershire sauce, ketchup, brown sugar, salt and pepper. Mix until these ingredients are thoroughly combined with the beef and vegetables.

Bring to a boil, reduce heat and simmer covered for about 5 minutes until the flavors are combined.
Then place the 2 halve of the loaf of bread on a baking sheet. Use a spoon to take out some of the bread from the center of the loaf.

Place the bread in the oven and bake the bread for approximately 5 minutes.
Then spoon the 1/2 of the sloppy joe mixtures into each loaf after this baking time.
Next add 1 cup of each type of cheese over the top of each loaf evenly.
Place back into the oven for approximately 5 minutes or until the cheese has melted.
Remove from the oven and allow time to cool. Then use a large knife to cut each loaf into slices for easy serving. Enjoy!
