favorite soup in a jar recipes?

[lakemom]

I want to do some soup (or casserole) in a jar recipes for my bils this year for Christmas since they are both single and live alone. Recipes that are crockpot compatible would be a huge bonus. I also have a pressure canner if you just have a great recipe that could be canned and just reheated at dinner time. I plan on getting them each a little (3qt? I think) crockpot too.

thanks
