I like their food and have bought quite a bit in bulk.
Keep in mind that it adds up to a lot of food, so unless you really like something and aren't likely to get sick of it and are out a lot of days you are going to have a lot of leftover tabouli.
I'd say that the instant potatos and beans, while good, have much cheaper competition that is nearly as good. The soups and pasta dishes (the chili mac and corn chowder both are awesome) are much better deals.
All of her food is a little bland, and for me a fair amount of spices are required to keep my morale up.
