Preheat the oven to 325 degrees. Generously grease a 9x13’’ pan
Whisk the eggs, milk, salt and pepper. (I use an electric mixer to make it easier).
Pour the egg mixture into the greased pan and bake for 18-22 minutes, or just until the center is set. Don’t over-cook.
Remove from oven and allow to cool before cutting into 12 squares.
Top each English muffin half with egg, cheese, meat, and the other half of the muffin. If you are consuming right away, heat the sandwiches at 350 degrees for about 5 minutes or until the cheese melts.
Wrap each sandwich individually in tinfoil, wax paper, or parchment paper and place them in a freezer safe resealable bag. Freeze for up to 1 month.
Thaw in fridge overnight, for best results. Remove paper and wrap sandwich in a paper towel. Microwave for 40 seconds - 1 minute on defrost (or 50% power). Flip the sandwich over and microwave for 10-30 seconds on high power, until warmed through.
You can also reheat the sandwiches in the oven at 350 degrees for about 10-15 minutes, or in the toaster oven.
