Crack egg into bowl and using the shell, breakup the yolk (this is optional, but the egg cooks faster when the yolk is broken)
Sprinkle with salt and pepper
Cover with paper towel (big enough to cover entire bowl)
Microwave for about 40-50 seconds. Basically, enough to fully cook your egg or mostly cooked.
Put on slice of ham and slice of cheese
Cover with paper towel again, back in microwave for about 20-30 seconds. This is just warming up your ham and your cheese is getting melty.
Now top with tortilla and back in microwave for 10-15 seconds. Just to warm tortilla up.
Lastly flip bowl over the palm of your hand where the tortilla is now in your palm or on a plate and the egg is on top.
Carefully fold the whole egg, ham, cheese, and tortilla in half and enjoy!
Notes
Since all microwaves are different, my times are suggestions. I recommend just standing next to the microwave and checkin in on your tasty breakfast to make sure it is to your liking. *DON'T forget the paper towel to cover the egg! You do not want an egg explosion in your microwave, believe me... not fun to clean up.
