Chick-fil-A Egg White Grill

Preheat oven to 400F. Place the bottom half of the English muffins onto a baking sheet and drizzle with 1 tablespoon of the oil. Set aside. Place the chicken breast onto a cutting board. Cover in parchment paper or plastic wrap, then using a meat mallet or bottom of a heavy skillet, pound to a uniform ¼-inch thickness. Then cut into 4 pieces. Season the chicken with salt, pepper, and lemon zest. In a medium non-stick pan, heat the oil over medium-high heat. Add the chicken and cook until golden brown and cooked through, about 3 minutes per side. Set a piece of chicken on top of each muffin base. Wipe down your skillet and reduce heat to medium low. Spray with the avocado oil then add ½ cup of egg whites and a pinch of salt. Swirl the pan so the eggs coat the bottom and cook until just set, about 2 minutes. Fold into an omelet and cut in half. Add on top of two of the chickens then repeat for the final two sandwiches. Add the cheese on top of the egg whites then place the muffin tops onto the sandwiches. Drizzle with remaining tablespoon of oil then place back into the oven until the cheese is melted and English muffins are slightly toasted, about 5 minutes.
