Spray a small glass dish with non-stick spray and crack whole egg and egg white into dish. Microwave for 45 seconds, stir, then microwave 30 more seconds or until firm - sprinkle with salt and pepper to taste.
Sprinkle tomato slices with salt and pepper and place on top of cooked eggs.
Wrap frozen sausage patty in paper towel and microwave for 60 seconds then place on top of tomato/egg dish.
To assemble sandwich, place one half of the English muffin on top of the dish then top with a large square of tin foil.
Flip the dish over and lay flat on the foil to reveal the egg/sausage/tomato components.
Top with second English muffin half and wrap tightly with foil to enjoy on the road.
Not taking this sandwich to go? Simply skip the foil and use a plate instead. :)
