The vegetable often confused with a fruit and used in salsa is the tomato. While commonly referred to as a vegetable in culinary contexts, tomatoes are botanically classified as fruits because they develop from the ovary of a flower and contain seeds. Their juicy flesh and tart flavor make them a popular ingredient in various dishes, particularly in salsas, where they provide freshness and acidity. Rich in vitamins C and K, as well as antioxidants, tomatoes contribute to both flavor and nutritional value in many cuisines.
