For avocado hummus, first finely puree chickpeas, olive oil, tahina, lime juice and garlic with a hand blender or in a stand mixer.
Mash avocados with a fork, add with cumin and 2/3 of the black sesame seeds. Season to taste with salt and pepper.
Sprinkle avocado hummus with chili flakes, fresh cilantro and remaining black sesame seeds. Optionally, drizzle with a little olive oil.
