Add the tahini and lemon juice to a food processor and process for about 30 seconds, until fully blended.
Add the olive oil, salt, cumin, paprika and garlic. Add any other spices you'd like at this point. Process for about 30-60 seconds. Scrape the sides down and process for another 30 seconds.
Add 1/2 of the chickpeas and process for about a minute. Then add the rest with a splash of water and process for a minute until the chickpeas are fully incorporated, scraping the sides down as needed. It may still be lumpy at this point, so add a little more water and process until it's at your desired consistency. Taste the mixture and adjust spices as needed. That's it!
