Preheat your oven to 350°F (176°C)

Preheat a griddle then add a pat of butter and melt over griddle surface. Place English muffins on the hot griddle to toast. Toast in batches if needed. When toasted as desired, transfer the top portion of the muffins to a work area, flip the bottom section over and place a slice of cheese on the bottom half then toast another minute to melt cheese.

Spray six sections of a muffin top pan with cooking spray then fill with liquid egg whites. Place into the hot oven to bake 15 minutes. Season cooked egg whites with salt and pepper, if desired.

While everything else is cooking, add a single layer of turkey bacon in the air fryer basket tray. Lightly spray with cooking spray or duck fat spray. Place into the air fryer, set at 400°F (204°C) and air fryer cook 12-15 minutes, flipping halfway through cooking.

Assemble sandwiches by adding any additional toppings or condiments (see full post for suggestions), a couple of slices of crispy air fried turkey bacon, egg white then top with the top toasted English muffin section and enjoy.
