Pre-heat the oven to 350 degrees and spray a muffin tin with cooking spray.
Crack one egg into each muffin tin and sprinkle with salt and pepper. For even baking, gently break the yolk using a fork or knife.
Bake eggs until egg whites are firm, 18-20 minutes.
While eggs are baking, begin assembling the sandwiches by placing the bottoms of each English muffin on a flat surface. Top each bottom half with one slice of cheese and once slice of ham.
Place one egg on top of the ham and cheese half then top with the second half of the English muffin.
For easy microwave reheating, wrap each sandwich individually in parchment paper then place in a resealable plastic bag to freeze. To reheat, simply place in the microwave for 60 seconds on full power or 1 1/2 minutes on 50% power.
