Guacamole Breakfast Sandwich

Add eggs to the skillet. Cook until white is set but yolk is still runny, about 2-3 minutes; season with salt and pepper, to taste. Place a slice of cheese over each egg during the last 30 seconds of cooking time; set aside.

With a butter knife, spread butter on each slice of bread. Place bread in the skillet and toast, flipping once, until golden brown, about 2-3 minutes.

To assemble the sandwiches, place 4 slices bread on a work surface. Spread with guacamole, topped with bacon, egg, cheese and another slice of bread.

Serve immediately.
