There's nothing quite like cooking food over an open flame. The techniques are simple and grilled food tastes amazing.
Steak, hamburgers, and hot dogs are the most popular foods to grill, and in general all beef products should be cooked over direct heat and with the grill on the high setting. The heat can be turned down slightly for hot dogs and thin cut steaks.
Grilling chicken takes a bit more time and should be done at a medium-heat setting. Chicken can easily dry out on a grill, so it's best to cook it slowly and brine it overnight or apply a marinade or sauce to keep it moist.
Grilling pork is similar to beef, use direct heat but turn down the temperature to medium-heat. Pork chops can cook quickly and depending on the thickness only require 2-4 minutes per side before they're done.
