1. Chicken: Cover the chicken breasts with plastic wrap and pound until each pieces is about a ¾ of an inch thick. Place the flour and salt and pepper in a shallow dish and gently toss each chicken breast in the dish to coat. Melt the butter in a large skillet over medium high heat; add the chicken and sauté for 3-5 minutes on each side, until golden brown, sprinkling each side with the lemon pepper directly in the pan. When the chicken is golden brown and cooked through, transfer to a plate.

2. Asparagus and Lemons: Add the chopped asparagus to the pan. Sauté for a few minutes until bright green and tender crisp. Remove from the pan and set aside. Lay the lemon slices flat on the bottom of the pan and cook for a few minutes on each side without stirring so that they caramelize and pick up the browned bits left in the pan from the chicken and butter. (NOTE: adding a tiny pat of butter in with the lemons also helps prevent sticking and promote browning.) Remove the lemons from the pan and set aside.

3. Assembly: Layer all the ingredients back into the skillet - asparagus, chicken, and lemon slices on top.
