Chop the cucumber and tomato, then slice the olives and chop the parsley.
Spread the hummus in the bottom of your dish, then drop spoonfuls of the greek yogurt, gently spreading it outward, about ½ inch from the edge of the hummus layer.
Scatter the cucumber, tomato, and olives and feta in layers over the top. Then sprinkle with parsley.
Chill for 1 hour or until ready to serve. Serve with crackers, veggies, or your favorite dippers.
