Set aside 2 tablespoons of chickpeas for garnish.In a food processor, combine 2 cans (15 ounces each) chickpeas (drained), ⅓ cup aquafaba, 2 tablespoons lemon juice, ½ clove garlic, and ¾ teaspoon salt. Blend for 3 minutes, scraping down the sides as needed.
Add ⅓ cup tahini, ½ teaspoon ground cumin, and ¼ cup cold water. Blend for another 2 minutes.
Pour in 1 tablespoon olive oil and some more water if needed. Blend for 2 more minutes, until smooth and creamy. Taste and adjust the salt and consistency by adding a little more water if needed.
Spread the hummus on a plate or in a bowl. Use the back of a spoon to create a well in the center. Drizzle with olive oil, top with the reserved chickpeas, and sprinkle with 1 tablespoon flat-leaf parsley.
