Make sure any meat you cook is completely defrosted before cooking, otherwise you'll kill the finishing on your grill. How long to cook meat mainly depends on the thickness and its fat content. Be careful not to overcook meat, the grill cooks so fast that meat(especially low fat) can go from undercooked to overcooked in less than 30 seconds. The hamburgers and other burgers come out so moist that you can just salt them up and eat them like you would a steak, no ketchup or bun necessary. If you're cooking other veggies you can cook them right after cooking the burgers without washing the grill. Hamburgers and lamb burgers leave a greasy film that works as a great seasoning for other veggies. You can also add some Extra Virgin Olive Oil to some of the meats like chicken, pork chops etc. If you cook something like pork chops that has a bone, trim the meat off the bone before cooking. You'll want the top of the grill to press against meat while cooking, not bone.
