Lightly fry the Canadian bacon slices in a 12 inch skillet and set aside to keep warm. Melt butter over medium heat in same skillet. Fry eggs (as many as you can fit at a time) in the butter over low-medium heat, breaking yolks before flipping. Top each egg with 2 slices of Canadian bacon and 1 slice of cheese. When cheese has melted, place egg on English muffins. Repeat with remaining eggs, if necessary. Enjoy!
