In a food processor, add the Tahini paste and the lemon juice.  Pulse to combine.

Remove skins from drained chickpeas. (if you don't, the Hummus will be less smooth but will taste the same.  It's a texture thing!)

Add the Chickpeas and garlic  to the processor and pulse to combine.  Scrape down the sides occasionally.  the Mixture will be thick, adding water will loosen the dip to the consistency you like. 

Optional: you could add 2 tablespoons of olive oil.  I don't because it adds extra calories and not a lot of extra flavor.  (1 tablespon of oil is 140 calories!)

Add salt, pepper and sugar to taste.

Enjoy!
