Make a brine 2 days before you intend to cook your chicken. Put cup of kosher salt in a large stock pot (like you use to cook spaghetti or sauce) Add water and 3 cloves of minced garlic (save 4th for sauce) Chop up at least half of the bunch of basil and add to water. If you have any other fresh herbs like tarragon and rosemary add them to the mix as well. Add lemon juice. Let sit in covered pot for at least two days, stirring once a day.
Turn on gas grill or ready a charcoal grill. Empty pot of all liquid into a strainer to catch chicken. Wipe down chicken and place on grill on medium high flame and cook on each side until golden grill marks. It can be 95% done at 145 Degrees F, place in a pan and cover tightly with foil or use a lid. Chicken will continue to cook as it rests in pan and temp should be 160/165 Degrees F internally. Next grill all zucchini until tender and have grill marks on both sides. Let cool and slice the rounds into half. You can cut your chicken into smaller pieces or leave whole. Lay them in pan and add zucchini halves across the chicken. Chiffonade some of the fresh basil for decorative touch to sprinkle on chicken.
Melt butter in pan, add white wine, cherry tomatoes cooking over medium low heat and stirring until the tomatoes cook and pop. You can also add more lemon juice if you like or replace white wine with all lemon juice, your choice. Add pinches of salt and black pepper to taste. Pour over chicken and zucchini, sprinkle on chiffonade basil and enjoy!
