Preheat broiler on oven. Split the English muffins and place on a large baking sheet. Toast both sides under broiler (1-2 minutes). Set English muffins aside. Turn off broiler and preheat oven to 400 degrees.
Cook sausage patties in a frying pan until completely cooked and nicely browned. Set sausage patties aside.
Crack all the eggs into a large measuring cup, add salt and pepper (to taste), and whisk thoroughly. Spray a 12-cup muffin tin with cooking spray and pour the egg mixture evenly into the 12 cups. Bake for 10-12 minutes, or until the eggs are set.
Remove eggs from oven and top each cup evenly with the shredded cheese. Return to oven until cheese is just melted. Remove from oven.
Assemble the sandwiches in the following order: 1 English muffin half, one egg and cheese round, one sausage patty, 1 English muffin half.
Once the sandwiches are cool, wrap each one individually in plastic wrap and place each wrapped sandwich into a resealable freezer bag.
