I had heard when canning homemade soup you just need to cook it like you are going to serve it, then fill the jars and turn them upside down. Does this work to create a proper seal?
Heather, I wouldn't do or trust it. Read the archived information below. I have a book about canning from Ball (Ball Blue Book of Preserving). It has very detailed information about how to can/preserve different things. You don't want to mess around with this, whoever consumes the food could get deathly ill!

I always add cabbage to my veggie soup even when I make my WW version without any meat. It really adds a lot to it. If I don't have a head of cabbage I just buy a small bag of shredded cabbage (cole slaw) and add some of that.
