01 - Preheat a griddle to medium heat.

03 - Whisk together eggs, milk, salt, and pepper in a bowl.
04 - Melt 2 tablespoons butter on the griddle. Pour the egg mixture onto the griddle and gently scramble until just set. Divide into 4 portions.
05 - Toast English muffin halves, cut side down, on the griddle until golden brown.
06 - Spread mayonnaise or butter on each muffin half if desired. Place a portion of scrambled eggs on the bottom half, top with a slice of cheese and 2 bacon strips. Cover with the top half of the muffin.
