This is so easy, I'm not sure it counts as a recipe. Take chicken breasts and poke several times with a fork and put into a large ziploc bag. Then pour zesty Italian dressing in the bag and squeeze the air out of the bag and seal. Marinate chicken overnight in fridge. Then cook on an outdoor grill. The thinner the chicken breast, the more evenly they cook. I cut my chicken breasts horizontally in half to make two thinner pieces. This is best when grilled on an outdoor grill.
