The POP foodcourt has hummus with bagel chips in the 'grab and go' section. You can also get hummus at Boma (a couple different flavors) and at Saana at the AKL.
Boma has some exotic flavors of hummus actually! I believe there is one that is red peppererd flavor, I really can't remember the others aside from just plain, regular hummus. Then there are 2 other flavors...all of them are good!
If you are on the dining plan, then head to Sunshine Seasons. On our last trip I was able to get a big tub of hummus and a whole bag of soft mini pitas for two snack credits!!! They were a great pick up for us between lunch and dinner. The amount of food was huge for two snack credits.
Hummus is YUMMUS! Seriously, I love making it, especially b/c you can experiment with flavors and get the perfect recipe made for your taste (mine is ALOT of garlic!! Won't be going on any dates after eating it lol!)
Sanna had hummus in the bread sampler, and Tusker House does
When researching the Moroccan pavillion but Restaurant Marrakesh and Tangerience Cafe had humus
A few years ago I got a big portion of Hummus at Tangierine Cafe ($2.00). It came with a small serving of pita chips. I still had hummus left, but no chips, so bought a delicious piece of fresh-off-the-grill flatbread (huge) for a dollar.
I have discovered that for $3.00 I can have lunch!
