Chop all of your veggies and set them aside.
Spread the hummus in a smooth layer in the bottom of 12-inch round platter or serving dish (you can also use a pie dish or similar serving dish).
Carefully spread the tzatziki over the hummus, leaving a ½-inch border around the sides, so you can still see the hummus.
Sprinkle the feta cheese, cucumbers, tomatoes, kalamata olives and red onion over the top. Drizzle olive oil over the top and finish with a sprinkle of sea salt.
Serve with crackers, fresh veggies and/or whole wheat pita for dipping.
