Slow Cooker Veggie Soup

I had some veggies that had to be used up, so I basically just tossed them together. It was better than I thought it would be.

1/2 large onion, chopped
2 cloves garlic, minced
1/2 head green cabbage, chopped
2 gold potatoes, peeled and chopped
2 carrots, peeled and sliced
32 oz. vegetable broth
2 c water
6 oz. tomato paste
1/2 tsp oregano
1 tsp parsley
1 tsp sugar (to offset the tomato taste)
Salt & pepper to taste

Toss everything into the slow cooker, and cook on low 6-8 hours, until all of the vegetables are tender.
