In a food processor, puree:
1 16-oz. can of garbanzo beans (drain and save liquid)
1–2 Tbsp. tahini
2 cloves chopped garlic
2 Tbsp. olive oil
3–5 tsp. lemon juice, depending on taste
Add a pinch of cayenne pepper and salt.
If the mixture seems too thick, add ¼ cup of the liquid from the garbanzo beans.

Hummus has roughly the same number of calories as cream cheese.
