Instructions
Preheat the oven to 400 degrees F and start preparing your ingredients.
Cut the buns in half and spread some mayo or butter on the buns to make them crispier. Bake for 5 minutes, and then keep them aside.
Add olive oil, beef, onion, and green pepper to a skillet. Cook at medium flame, and when the beef changes color, add the garlic. Sauté it for 2 minutes.
Add the beef broth, cornstarch, and beef bouillon to a cup and mix them. Add it to the meat and mix it continuously.
Put the ketchup, Worcestershire sauce, Dijon, and the remaining seasonings in the meat.
Cook for 5 to 7 minutes, and then add the cheddar cheese.
Add the cooked beef to the buns and top it with provolone cheese. Bake it for 10 minutes at 400 degrees F and serve it immediately hot and fresh from the oven.
