Deli meats, also known as cold cuts or lunch meats, are pre-cooked or cured meats that are sliced and served cold. Common types include ham, turkey, salami, and roast beef. They are often used in sandwiches, salads, and platters, providing convenience and flavor. These meats are typically processed with various methods, such as smoking, curing, or brining, to enhance taste and preserve freshness. While deli meats can be a quick meal option, it's important to consider their sodium and preservative content, as some varieties may contain additives like nitrates and nitrites.
