Step 1

Place a 9 1/2- to 11-inch nonstick skillet over medium heat and preheat for 2 to 3 minutes. Spray the skillet for about 2 seconds with cooking spray, then cook the ham or Canadian bacon on each side until hot and lightly browned. Transfer to a plate and set aside.

Step 2

Place the bread in the skillet to toast for about 30 seconds on each side. Set aside.

Step 3

Spray the skillet again with cooking spray until very well coated, about 5 seconds. (You can also substitute melted butter for the cooking spray if you like.) Whisk the eggs in a small bowl and pour into the skillet. Season with salt and pepper. Reduce the heat to low and allow the egg to firm up, about 1 minute. While the top of the egg is still wet, place both slices of bread in the center next to each other. The egg will firm up around them.

Step 4

Flip the entire round of egg with the bread stuck to it. Now the 2 slices are covered by the egg and it will look like an omelet from the top. Fold the edges of the egg over the bread, leaving them still connected to the the bread slices. Top the bread slice on the left with the cheese. Top the other bread slice with the ham or Canadian bacon, folding or overlapping slightly if necessary to fit inside the bread. Once the egg is set, gently fold the right slice of bread over the other to close the sandwich. Slide the sandwich onto a plate and, voila, you have a perfect breakfast sandwich.
