This has been our favorite grilled chicken recipe for twenty-some years.  It's great as an entree or sliced up in a green salad. 

Marinade: 

1/2 cup olive oil

1/2 cup dry white wine

1/2 cup regular or gluten-free soy sauce

2 tbsp freshly grated ginger

1 tbsp dry mustard

1 tsp freshly ground black pepper

4 cloves garlic, crushed

1/2 cup chopped green onions

3 tbsp sesame seeds

6 boneless, skinless chicken breasts

Combine marinade ingredients in bowl. Mix well. Put chicken and marinade in a large zip-lock bag.  Squeeze out air and seal.  Marinate in refrigerator for 4 to 8 hours.  Hint for additional meals: freeze uncooked extra chicken breasts in the marinade as soon as the marinade is finished. 

Preheat the grill for medium-hot heat.  Lightly oil the grill.  Grill chicken 8 to 10 minutes per side or until juices run clear.
