Oasis brand makes a Zero Fat Hoummus. I picked it up at a Whole Foods in Chicago, and ate it with celery sticks.
It is seriously good.
The variety I had was Oasis brand "Mediterranean Medley" It has sweet peppers, onions and other veggies in addition ot chickpeas. 2 tbsp had 18 calories and zero fat. 2 tbsp Sabra has 70 calories.
I ate the entire 10 oz. tub - a whopping 180 calories, and it was a satisfying lunch. I know that this thread isn't about diet advice, but a satisfying, a low-cal lunch, that you can grab and go in a neighborhood without kosher restaurants is something I treasure.
It isn't available everywhere, (http://www.omcfood.com/location.html)
