Method
- Brown the lean ground beef in a hot pan. Once browned, remove and set aside.
- In the same pan, melt butter and sauté diced onions, bell peppers, and mushrooms until browned.
- Mix beef broth, ketchup, salt, and pepper in a bowl; pour into sautéed veggies and simmer until thickened.
- Return the beef to the pan and mix well.
- Turn off heat and stir in provolone cheese until melted.
- Butter and toast brioche buns separately until golden.
- Fill toasted buns with the cheesy beef mixture and serve warm.
Notes
Feel free to adjust the amount of cheese to your liking, or add a touch of Worcestershire sauce for extra depth. For a spicier kick, add a pinch of red pepper flakes with the vegetables.
