Method
Cooking
- Brown the lean ground beef in a hot pan over medium-high heat until no pink remains and the edges begin to crisp, then transfer to a bowl.
- In the same pan, melt butter and sauté the diced onions, bell peppers, and mushrooms until browned, stirring frequently.
- Mix beef broth, cornstarch, ketchup, salt, and pepper; pour into sautéed veggies and simmer until thickened.
- Return the beef to the pan, mix well, and let flavors meld on low heat.
- 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
Use a hot pan for a good sear on the beef; sauté mushrooms until liquid evaporates. Adjust seasoning to taste.
