1Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the cooked meat, diced mushrooms, shredded cheese, and diced onions.
Beat the egg in a separate bowl and add it to the meat and mushroom mixture. Mix well to combine.
Take the slices of bread and remove the crusts if desired.
Flatten each slice of bread using a rolling pin.
Place a generous spoonful of the meat and mushroom mixture onto each slice of bread.
Roll up the bread slices tightly, securing the filling inside.
Place the stuffed bread rolls on a baking sheet lined with parchment paper.
Bake in the preheated oven for 15-20 minutes, or until the bread is golden brown and the filling is heated through.
Remove from the oven and let cool slightly before serving. Enjoy your Meat and Mushroom Stuffed Bread!
