Toast the English muffins, and then butter them to your liking.
6 English muffins, 1 tablespoon butter
Heat 1 tablespoon of butter in a large skillet over medium heat.
Once the butter has melted, cook the Canadian bacon slices in the pan for a minute or two on each side. Set the bacon aside on a plate.
6 slices Canadian bacon
Place a mason jar lid or metal ring mold in the center of the pan and spray with cooking spray. Crack 1 egg into the ring. Use a fork to gently break up the yolk. Season with salt.
6 eggs
Pour 1/4 cup of water into the pan around the ring, cover the pan, and cook for about 1 minute until the egg is cooked through.
Place the American cheese slices on the English muffin halves. Gently remove the ring from the egg and place on top of the cheese. Repeat for the remaining eggs.
6 slices American cheese
Top each egg with a slice of Canadian bacon. Then, close the sandwich with the other English muffin half.
