Cabbage and cauliflower soup.
Preparation time: 5 minutes
I made this soup some weeks back while cleaning out the crisper drawer: Half a cabbage, a wedge of red cabbage, some cauliflower, carrots. I used cider vinegar to kick up the flavor.
Because of the red cabbage, the soup took on a color resembling dirty dish water, so I never considered it ready for prime time. This is just one of those homely soups you keep in the freezer and serve to family as the need arises. Or perhaps one of those soups you eat yourself, since no one else in the house seems interested in cabbage soup that looks like dirty dish water.
