This is not what most people in the States think of when they think of salsa. This is pico de gallo, also called salsa fresca. You will find it at every local restaurant, and this recipe is exactly perfect and authentic. In fact, in our part of Mexico (central Pacific Coast), this sauce is always called 'Salsa Mexicana', and is never called 'pico de gallo', which is, I believe, Tex-Mex nomenclature.
