I got the marinade recipe off the Old Bay seasoning tin. It was fabulous! I used frozen chicken and it cooked perfectly.
2 boneless, skinless chicken breasts
1/4 cup oil
2 tbsp lemon juice
1 tbsp Old Bay seasoning
1 tsp parsley
1/4 tsp black pepper
Combine everything but chicken in a ziptop bag. Mix throughly and add chicken. Refrigerate 20-30 minutes turning over half way through.
Preheat grill to medium-high. Place chicken on grill for 5 minutes. Rotate chicken 1/4 turn and grill additional 5 minutes. Turn chicken over and repeat grill times. Baste chicken with marinade every time you rotate it. Test temperature in thickest part of breast. It should read about 175 deg.
Serve with cooked rice mixed with sauteed onions and a green salad.
