Grilled Lemon Walnut Chicken Print 8 LikeDislike By Tiffany Kingsley Summer’s here and it’s time to light up the grill! This Lemon Walnut Chicken is a delicious and easy summer dinner! You can start marinating the chicken in the morning, then grill it at dinnertime.I use some walnut oil for this recipe, because it gives the dish a unique flavor and provides you with more omega-3 fatty acids than most other nut oils. Because raw oil maintains its nutritional integrity more than cooked, set some aside to use as a dressing for a salad to go along with your chicken*. *Make sure not to use any that has been in contact with raw chicken.
