Pico de gallo is generally known as a fresh condiment made from chopped tomato, onion, and chiles (typically serranos or jalapeños). Other ingredients may also be added to the salsa, such as lime juice and chopped cilantro leaves. Many grocery stores carry ready-made pico de gallos in the refrigerated section.
