Ingredients

* boiled patatoes (cold)
* olives (black or green)
* ripe tomatoes
* finely chopped onions
* salt
* oregano or 3-5 basil leaves
  (not washed just cleaned)
* freshly battered extra-vergin olive oil and vinegar
  (please please do not use the so called "Italian dressing", which is fake)

Optional Ingredients

cubes of pecorino (sheep) cheese or mozzarella

Directions

Add tomatoes at the end, use cold potatoes, and do not put too much of anything: too much is not better, is just too much; anyway, this is not a minimalist salad either, so do not be stingy either: in medio stat virtus!
