Kendra's hummus with roasted eggplant

Here's the recipe I make every week...and it disappears every week! It's super cheap and takes 5 minutes and is soooo good. My good friend Kendra gave me the recipe. It pretty much sealed the friendship :)

1 large can garbanzo beans (chickpeas), drained
2-4 cloves garlic, crushed (or 1/2 tsp dried garlic)
1/6 cup water
2-4 Tbsp tahini (opt)
1 Tbsp olive oil
pinch salt
Lemon juice - start with 1/2 lemon and add to taste
1 eggplant, roasted and scooped from peel*

Dump. Purée with stick blender/blender/food processor. Dip.

* The eggplant is optional but SO stinkin' good. It's so creamy. Just wrap the eggplant in foil (well!) and toss it in the oven the next time you bake something. When it soft, it's done. Let cool completely in foil, then unwrap and add to hummus.
