This year our party went green and guests who came with their own mugs for soup were emailed an e-cookbook of the 8 different soups. This year we had vegetarian carrot-ginger and mushroom-barley soups. There was also a potato-garlic, cowboy soup (its sweet potato based!), and my moms famous chicken chili. Those were my favorites, and really the only ones I can remember right now.
The best part might actually be the leftovers we are always left with...I highly recommend the drunken goat cheese if you happen to be raiding my fridge.
Ok, so I know most people don't actually listen to the mixes, but if you EVER listen to one, make it this one.
