Drain and rinse garbanzo beans. Remove the outer shell of each bean with your fingers and discard shell. Add to food processor.
Along with the garbanzo beans, add the flesh of the avocado, tahini, lemon juice, garlic, cumin, paprika, cayenne, salt and pepper and a drizzle of olive oil. Pulse together until everything is combined.
If it is too thick, add a Tb of water at a time until desired consistency. I also like to add extra lemon juice. Taste for seasoning.
When done, layer hummus on a plate, making a small well in the center. Drizzle additional olive oil and sprinkle za'atar.
