This tasty crowd favorite is the perfect sandwich for parties, tailgates, game days, or backyard barbecues. It's easy to make, kid-friendly, and all-around comfort food.
Heat a large or cast iron skillet over medium-high. Add the ground beef and cook for 3-5 minutes or until browned. Break it up to prevent it from clumping.
Remove the beef from the pan and remove excess fat, especially if using regular ground beef. Use your best judgment.
Add the butter, onions, garlic, bell peppers, and green onions—saute for 1-2 minutes.
Return ground beef to the pan, and follow with the ketchup, Worcestershire sauce, white pepper, paprika, and Creole seasoning. Cook for about 2 minutes.
In a small cup, mix the beef stock and cornstarch and add to the beef mixture.
Cook for 4-5 minutes or until the liquid reduces some. Add salt and pepper to taste.
Turn off the heat, add the provolone cheese, and serve on toasted rolls or brioche buns.
