I usually grill chicken on 4th. Always grill bone in with skin on for juice and flavor. My favorite marinade is Italian dressing with a package of Kool Aide lemonade mixed in. Then I pepper the chick. on the grill.
Also have a rosemary marinade for pork tenderloin. 2 cups oj, 1/2 cup soy sauce, and add 5 tbl spoons of rosemary. Marinate for 12 hours and grill. Boil and strain marinade and use as sauce/gravy for the entree.
With everything but steak I brown both sides on high heat, and then move over to unlit side of grill and cook for about 25 minutes. This produces unbelievable results.
