My family has a stew recipe that I love to can. It is simple to prepare, and improves on flavor as it sits on your shelf.
cabbage (chop or shredded)
potatoes (large dice)
water (to cover)
pepper (to taste)
Simple, simple. Add everything together in the quantities you have on hand. Season only with pepper to your taste. Heat through and place into your hot sterile jars. Process at 10 lbs for 20 minutes. It is ready to eat as soon as it cools, or keep well for a few years. This is one of the few recipes that doesn't loose flavor after a year.
If you add carrots or any other root veggies, I would suggest eating it sooner rather then later. But if you keep it super simple, no worries.
