The version I’ve been eating for a couple of decades goes like this: Good bread is key, I like olive sourdough or something chewy with grain. Layer of avocado, layer of hummus, sprinkle feta cheese, sliced tomatoes, lettuce on the side as a “chaser” and... yum. I guess that’s “cultural” in that it’s just adding avocado to a Greek thing.
