This will cut clean-up time immeasureably. Have items you need at hand in your cooking space next to the grill. Don't leave the grill unattended to run in the house fetching anything. Believe me, there's always a little kid lurking somewhere nearby ready to burn themselves or grab the spatula and flip a burger or two into the grass. Have a large trash container ready with a plastic sack inside for disposal of used plates, napkins and cans.
Kabobs are a wonderfully easy barbecue meal.
On bamboo skewers, rotate chunks of steak, tomato, pineapple, onion, carrot and other firm vegetables and fruit. Brush with a marinating sauce to bring out luscious flavor blends. Have a large washtub of ice and cold canned drinks placed outside. Keeping guests out of your refrigerator will keep other foods cold. Now that everything's under control, your only requirement is to enjoy yourself.
