Firstly, Prepare the hummus. Place all hummus dip ingredients in a food processor; process for 2 minutes, scrape down the sides, and continue to process until smooth and thoroughly combined, about 4 minutes. If you like thinner hummus, add 1 more tablespoon of water and process it until combined.
Spoon prepared hummus into a deep salad bowl or trifle bowl.
Add yogurt over hummus.
Layer artichoke hearts over the yogurt.
Add sliced black olives.
Layer lettuce leaves over olives; add tomatoes and feta cheese.
Sprinkle with a bit of extra virgin olive oil (optional) and then serve with toasted garlic bread slices.
