Pepperoni and mushroom omelette is a delicious and filling breakfast dish that is perfect for weekends. To make this omelette, you will need eggs, sliced pepperoni, sliced mushrooms, shredded cheddar cheese, and butter. Melt the butter in a non-stick skillet over medium heat. Whisk the eggs in a bowl and pour them into the skillet. Add the pepperoni slices and sliced mushrooms to one half of the omelette. Sprinkle the shredded cheddar cheese over the top. Use a spatula to fold the other half of the omelette over the filling. Cook for 2-3 minutes or until the cheese is melted and the eggs are cooked through. Serve hot and enjoy!
