Pre-heat oven to 400 degrees. Spray a muffin tin with non-stick cooking spray.
Divide Canadian bacon, spinach, and red pepper evenly among the 12 muffin molds. Fill the molds with egg whites until the egg whites reach about 1/4" below the top of each mold. Top with salt and seasoning.
Bake at 400 degrees for 13-16 minutes or until the egg whites are solid and cooked through.
