Follow these simple steps to prepare your Easy Make-Ahead Breakfast Sandwich:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Baking Sheet: Lightly grease a baking sheet or line it with parchment paper for easier cleanup.
3. Whisk Eggs: In a large mixing bowl, whisk together the eggs, adding salt and pepper to taste.
4. Cook Eggs: Pour the whisked eggs into a heated non-stick skillet over medium heat. Scramble the eggs until fully cooked, approximately 3-5 minutes.
5. Assemble Sandwiches: On each English muffin half, place a slice of cheese followed by a scoop of scrambled eggs and your choice of bacon or sausage. Top with the other half of the muffin.
6. Bake: Place assembled sandwiches on the prepared baking sheet. Bake in the oven for about 10 minutes, or until the cheese is melted and the muffins are warm.
7. Cool and Wrap: Remove the sandwiches from the oven and let them cool for a few minutes. Wrap each sandwich tightly in foil or plastic wrap for storage.
8. Store: Place in the refrigerator for up to a week. For longer storage, you can freeze them for up to three months.
9. Reheat: To serve, unwrap and heat one sandwich in the microwave for about 1-2 minutes, or until warmed through.
