DO NOT cut or chop the Feta, just throw the slab on top of your salad, drizzle with a good amount of quality olive oil and a generous amount of oregano and cracked pepper & serve.
Tips: Cucumbers and toms should be equal amount & red onion1/2 to 1/3 of this amount. There should be enough for 8-10 olives per person (no that is not over kill as the olives neutralize the citrus and feta).
