On a mostly flat platter or plate, spread the entire container of hummus out in a thin layer. Then spread about half of the container of tzatziki in a think layer on top of the hummus leaving about a 1/2 inch border of hummus.
Next layer on the tomatoes, cucumbers, peperonchini peppers, olives, green onions, and feta cheese leaving a small border on each layer.
Mix the olive oil and seasoning together then drizzle over the top of the dip letting it drip down the sides and settle on the hummus.
Chill for up to 3 hours. Serve with pita chips, pita bread triangles, cucumber slices, bell pepper strips, etc. ENJOY!
