Let's start by giving a simple explanation to what pico de gallo is; it translates to "rooster's beak" and it is a chucky Mexican salsa that is used as a finishing touch on several dishes to add a touch of brightness. I've also seen it referred to as "salsa fresca," it uses freshly riped and diced tomatoes, onion, cilantro and lemon juice. Sometimes, people add diced jalapeño as well, but I don't like jalapeños, so I omit them.
