Shred the cucumber on a box grater, toss with a large pinch of salt and let drain in a strainer for 10 minutes. Squeeze out any remaining liquid. Mix the drained cucumber with the yogurt, olive oil, garlic and mint in a medium bowl
Toss together the parsley, olives, lemon zest and scallions in a small bowl. Place the artichokes in a piece of cheesecloth or in a strainer and squeeze dry. Repeat with the peppers.
Layer the dip in a medium 3-quart clear glass trifle bowl or your favorite small serving bowl. Spread out the artichokes on the bottom, then top, in even layers, with the cucumber-yogurt mixture, peppers, pita chips, hummus, feta and the olive-herb mixture.
Wrap and refrigerate until chilled, at least 1 hour or overnight (if refrigerating overnight then top with the olive-herb mixture right before serving). Serve with pita chips.
