Add all the ingredients to a blender or a food processor.
Blend to make smooth hummus. Scrape the sides of the blender a few times while blending.
Add some more ice-cold water if needed to blend the hummus.
Check for salt and lemon juice and add more if needed.
Transfer the hummus to a serving bowl. Drizzle some extra virgin olive oil and top with chopped parsley, red pepper flakes, cooked chickpeas, and olives.
