Add a fruit of your choice, like grapes, pomelo, berries etc.
Add nuts of your choice instead of pine nuts.
If you don't get Greek yogurt, then use plain yogurt. Strain in a cheesecloth to remove excess water (whey).
If you use small lemons that are available in India or Kenya, use less of the lemon juice as its more sour than the big Meyer or Sorrento type lemons.
This salad makes a great party or picnic salad.
