Kosher salt and freshly ground black pepperto taste
Preheat oven to 375 degrees. Lightly oil six 10-ounce ramekins or coat with nonstick spray and place onto a baking sheet.
Add one egg to each ramekin, beating slightly. Season with salt and pepper, to taste. Place into oven and bake until egg whites are cooked through, about 12-14 minutes.
Place one egg over the muffin bottom. Top with two slices of ham and one slice of cheese, and then cover with another muffin top to create a sandwich. Repeat with remaining English muffins to make six sandwiches. Wrap tightly in plastic wrap and place in the freezer.
To reheat, remove plastic wrap from the frozen sandwich and wrap in a paper towel. Place into microwave for 1-2 minutes, or until heated through completely. Serve immediately.
