Cooking on a barbecue, also known as ROASTING, is the process of cooking food over an open flame or hot coals. This method of cooking has been used for centuries and is still popular today. ROASTING is often used to cook meats, vegetables, and other foods that require high heat. The food is placed directly on the grill and cooked until it is done. The heat from the fire gives the food a smoky flavor and can be used to create a variety of dishes.
