I'm setting out a Christmas buffet this year. There are a few vegetarians/pescetarians in the group. I am so far having a ham, sandwich rolls, mac and cheese, shrimp tray, scallops and bacon, and assorted cheese/fruit plate. I'm looking for a soup recipe that can go with the above that will round out the vegetarian meal. Something simple but a bit special and different? I can set it out in a crock pot, but prefer to cook it on the stove as I may be using the Instant pot for the mac and cheese. Or something I can do the day before.
