In 1953, the Mexican communist painter Frida Kahlo painted this Naturaleza Muerta Con Sandias (Still Life with Watermelon), coming close to the ingredients of a pico de gallo, combining fruit and peppers, in ever changing combinations, depending on the region. Sometimes it is closer to a (fruit) salad than a sauce, especially when the pieces are roughly chopped in not too small pieces. (Artist suggestion from the wonderful Feasting on Art site.)
Try the similar salsa fresca.
Or the green mango variation.
