I found a jar of something that purports to be dill pickles at Lidl the other day. I haven't opened them to try them out yet, but they have all the right spices in the jar, so it should be okay. They had loads of pickle products--some of them were sweet and might be a good substitute for bread and butter pickles, but I made some of those myself using a mix that you make in the fridge that my Mom sent me, and I still have two jars left!
Also, someone mentioned somewhere that the little rostbratwurst (or something like that) in the chilled food section tastes a lot like Jimmy Dean-style sausage. I tried some, and it does! I wasn't feeling motivated enough to make biscuits and gravy, but I think they would convey the appropriate taste just fine.
