Heirloom tomatoes are a variety of tomatoes grown from seeds passed down through generations, often prized for their rich flavors, vibrant colors, and unique shapes. Typically originating from both local agricultural traditions and intentional preservation, heirloom tomatoes are staples in Mediterranean, American, and other global cuisines. Nutritionally, they are low in calories yet packed with beneficial compounds. A medium heirloom tomato provides around 22 calories, 1 gram of protein, and 5 grams of carbohydrates.

Their thin skins and juicy texture make them ideal for salads, sandwiches, soups, and salsa, as well as a key ingredient in fresh summer recipes.
