Ingredients

The following ingredients have 4 Servings
  • 1 lb ground beef
  • 1 small yellow onion (diced)
  • 1 small green pepper (diced)
  • 8 oz cremini mushrooms (diced)
  • 2 tbsp ketchup
  • 1 tbsp Worcestershire sauce
  • 2 to 4 tbsp A1 sauce (depending on how strong you want the flavor)
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 1 tbsp cornstarch
  • 1 cup beef broth
  • 8 oz provolone cheese (sliced)
  • 6 sesame seed bakery hamburger buns

Instruction

  • In a large skillet over medium heat add ground beef and cook while breaking apart until no longer pink. Drain grease.
  • Return beef to the skillet then add onions, green peppers, and mushrooms. Cook for an additional 5 to 7 minutes, or until onions are tender.
  • In a small separate bowl combine beef broth and cornstarch. Whisk until no lumps remain. Pour broth over meat and stir well.
  • Add ketchup, Worcestershire sauce, A1 sauce, salt, and pepper. Stir well. Let cook until most of the liquid has been absorbed, about 5 minutes.TIP: The A1 sauce has a strong flavor. Start with 2 tbsp sauce and increase to 4 tbsp if you want your meat mixture to be bolder in flavor.
  • Turn off the heat to the burner. Add sliced provolone cheese to the top of the beef and allow to melt.
  • Serve meat and cheese mixture on sesame seed hamburger buns.
