Drain the canned chickpeas, reserving the liquid. If using cooked chickpeas, reserve about 1 cup of the cooking liquid.
Using your thumb and pointer finger, gently pinch or squeeze each chickpea, to remove the waxy outer layer. Discard the skins and place the chickpeas in a food processor (fitted with a blade attachment).
Also add to the food processor: the tahini, olive oil, garlic, lemon juice and Greek Girls Seasoning.
Process the mixture until it is smooth and creamy. Scrape down the sides several times during processing. Add the reserved liquid as needed to reach desired consistency.
Add salt to taste (optional).
Garnish asdesired. Serve at room temperature. Makes about 1½ cups.
