a can of whole chick peas, rinsed and drained,
lemon juice,
cumin,
olive oil,
tahini,
maybe some garlic,
maybe some crushed red peppers or other pepper,
maybe some dill.
Dump them into a food processor and taste once in a while to make sure you like it. You can add whatever you want to it.
I like to present it in a bowl with a few olives on the side, a little pool of olive oil in the center and dusted with paprika for effect.
Cheap and quick. I can pull it off in under 5 min.
