I'm posting a link for canning caramelized onions. I chopped up 10# last night, threw them in the crock pot for 12 hours with some butter and olive oil, and ended up using some for the beef stew I made for this evening. They are WONDERFUL and make the whole house smell amazing. I ran out of time to can them (I'll be using half-pint jars, pressure canning them at 14# for 70 minutes) but I can easily heat them up again to can tomorrow. It was easy as can be, and we'll use them in everything from scrambled eggs to roast beef sandwiches.

I'm posting a link because there are a lot of photos, and lots of additional information in the comments.
