This thread made me realize that I almost never buy packaged items at Whole Foods...I always buy prepared foods! What can I say, we're lucky enough to have the flagship Whole Foods, so we get kick rear food stations. That being said, I know some of the larger WF's out there carry some of the same prepared foods as ours, so I wanted to recommend you keep an eye out for these few items:
Chantilly Cream Cake -- it is a chantilly cream frosting (cream cheese, mascarpone, etc), with a layer of real berries in the center layer. DRROOOOL. Can be expensive if you get the whole cake, but I know the bakeries often sell slices of these as well. It is the BOMB, and they use natural ingredients, not weird hydrogenated variety stuff
Crab & Butternut Squash Bisque (in one of the soup stations) -- to die for. And I don't even care for crab very much. Less sweet, more savory than regular Butternut Squash bisque. But very rich, a meal in itself
Pizza Dough -- if they have a pizza station, they'll sell you a ball of their very tasty pizza dough. Ours offers it both frozen and unfrozen.
Two Bite Brownies -- this is packaged by Whole Foods, so probably more widely available. Very moist and chocolatey.
Also, if they have a real bakery (not an outsourced one), DH goes nutso for their cannolis. Says they're the best he's ever had.
I do buy all my spices either here or at a similar store to Whole Foods. Since they're sold in bulk bins, I save a lot of money on spices vs buying them in jars from a grocery shelf. Also in the bulk bin section are cheaper Organic flours and grains, and I like their "self serve" maple syrup.
