This is a tradional Pico de Gallo recipe that has been in my family for several generations. Many current recipes are variations of this simple one, and their taste is cluttered by garlic or other spices not usually included in the traditional recipe. This makes a great dip for tortilla chips, or in a layered bean dip. One can make great guacamole by smoothing out ripe avocadoes and adding this pico with a little more lime juice and salt to taste. I use a minimum of salt, so you may need to add more to suit your taste.
