Make the hummus.Place chickpeas in the bowl of a food processor. Blend them alone until they become powder-like, scraping down the sides as needed. Add lemon juice, tahini, garlic cloves and salt and ice cubes, and blend for about 5 minutes until smooth.
Spoon the hummus onto a shallow serving bowl, and spread the hummus with the back of a spoon. Add a layer of Karoun Labne, followed by cherry tomatoes, cucumbers, feta cheese, olives and green onions.
Drizzle olive oil on top right before serving, and enjoy with pita chips.
