Brown sausage on medium heat in a skillet, crumbling the sausage as it cooks. Remove sausage from pan. Take 1 egg and separate the egg white from egg yolk in separate bowls. Set the bowl with egg whites to the side. In the skillet you cooked the sausage, add the remaining 2 eggs and egg yolk. Cook on medium low heat, scrambling the eggs. Once cooked, remove from heat

Cut puff pastry sheets into 6 rectangles, there will be a total of 12 rectangles once you cut both puff pastry sheets. Unwrap the American cheese and tear each slice into 2, making a total of 6 slices of cheese

On a parchment lined baking sheet, place 3 of the rectangular puff pastry sheets evenly down. Layer on the cheese, eggs, and sausage. Top with another rectangular puff pastry sheet and crimp the edges together with a fork. Glaze the top of the sealed puff pastry with egg whites and set to the side. Repeat this step with a second baking sheet and remaining ingredients (you will have extra crumbled sausage left over).

Place the baking sheets in the middle of a preheated oven at 400 degrees. Bake for 20 minutes or until golden brown
