I found this online over a year ago and it's a delicious and simple soup. I haven't canned it yet but plan to.

PEASANT CABBAGE TOMATO SOUP

Hands-on time: 15 minutes
Time to table: 30 minutes
Makes 6 cups

1 tablespoon olive oil
1 large onion, chopped
1/2 head of cabbage (a whole head weighs about 2 1/2 pounds), chopped
Salt to taste
15 ounce can diced tomatoes
equivalent of 2 cans of broth (or water plus bouillon)
Tabasco to taste (this is important)
Brown sugar to taste (about a tablespoon , can uses sweetener)

In a large pot or Dutch oven, heat the oil til shimmery on MEDIUM HIGH. Add the onion and stir to coat with fat. Cook, stirring frequently. Add the cabbage as it's prepped, stirring to coat. When the onion and cabbage are beginning to soften, add the salt, tomato and broth or water/bouillon. Reduce heat to MEDIUM, cover and let cook for about 15 minutes or until cabbage is soft but still holds its structure. Stir in the tabasco and sugar.
