as request, heres a very basic hummus recipe. you can make your variations by adding roasted red peppers, black beans, olives, more garilic, chilis, etc...and remember, a good quality tahini, i think, is key to a great hummus. go ahead and double dip (we all do it anyway!)
Drain chickpeas and set aside liquid from can. Combine remaining ingredients in blender or food processor. Add 1/4 cup of liquid from chickpeas. Blend for 3-5 minutes on low until thoroughly mixed and smooth.
Place in serving bowl, and create a shallow well in the center of the hummus.
Add a small amount (1-2 tablespoons) of olive oil in the well. Garnish with parsley (optional).
