Red pepper and cilantro hummus

This recipe is from my aunt Gail. It's really tasty, and uses no oil!

Ingredients:

-1 (15oz) can garbanzo beans (reserve the liquid)
-4 oz jarred roasted red peppers (or sweet cherry peppers if you can find them)
-1/2 C cilantro
-1 clove garlic
-3 T lemon juice
-1 tsp vinegar (I used balsamic)
-several dashes cumin, red pepper, salt
-1.5 T tahini

Steps:
Blend all of the above to desired consistency, adding 1/3-1/2 the reserved garbanzo bean liquid (more if necessary)

Serve w/ veggies, on sandwiches, or with crackers.
