This is the chicken recipe that I use for Grilled Ranch Chicken & Veggie Sandwiches. The chicken is great as a main dish by itself as well.
*4 boneless, skinless chicken breasts
*1 packet (1 oz.) dry Ranch dressing mix
*2 Tablespoons all-purpose flour
Heat a grill pan over medium heat until very hot. Remove 2 teaspoons from the Ranch dressing mix and discard. Pour the remaining Ranch dressing mix into a bowl. Combine the flour. Mix well with a pastry blender or fork.
Dip the chicken pieces in the flour mixture, coating both sides. Shake off the excess. Lightly spray the chicken pieces with cooking spray.
Spray the hot grill pan with cooking spray. Place chicken in hot grill pan, and cook about 7 minutes per side until chicken is not longer pink in the middle.
