To prepare the garlic, slice the head(s) in half cross-wise, drizzle the exposed cloves with olive oil and season with salt and pepper. For whole cloves trim the base of the head and remove the outer layers before seasoning. Wrap garlic in foil and roast on a baking sheet at 400ºF (200ºC) for 40 minutes. Let cool, remove cloves from their skins and set aside.
In a 4-cup food processor, add chickpeas, tahini, garlic, lemon juice and salt and blend until smooth, scraping down the sides with a spatula as needed.
Add water and olive oil and continue to blend for another 2-3 minutes, adding a little more water as needed to reach desired consistency.
Transfer to serving bowl and garnish with your toppings of choice. Enjoy!
