Diced tomatoes are small, cube-shaped pieces of tomatoes that are often used in cooking. They can be found canned or fresh, and are commonly used in a variety of dishes such as soups, stews, and sauces. Diced tomatoes add flavor, moisture, and color to meals, making them a versatile ingredient in many recipes. Canned diced tomatoes are typically packed in their own juice or with added seasonings, which enhances their taste. They are a convenient option for home cooks, as they save time compared to chopping fresh tomatoes. Diced tomatoes are also a good source of vitamins, particularly vitamin C and vitamin A.
