Heat a skillet over medium-high heat and cook the back bacon slices for 1-2 minutes on each side, until they are nicely browned. Set aside the cooked bacon.
Turn on your oven’s broiler and set it to high. Spread butter over each half of the English muffins and place them cut side up on a baking sheet. Broil the muffins on the top rack for 1-3 minutes until they are golden and toasted.
To assemble, place a slice of back bacon on each toasted English muffin half, followed by a poached egg. Generously ladle hollandaise sauce over the top, and garnish with chopped chives for a finishing touch.
