Since it's Passover, how about a hearty gefilte fish soup?
1 jar gefilte fish (regular or sweetened as preferred)
2 large carrot
1 medium celery
1 large white onion
2 small cans tomato juice, approx.
1 small can tomato sauce, optional
Black pepper
Dash of paprika
NOTE: You can find jarred gefilte fish in your grocery's ethnic section, usually close to the chow mein. They may have gefilte fish, or they may have something called "whitefish and pike." Try whichever one you think you will enjoy more. Also, it doesn't matter terribly if you get the stuff in liquid versus jellied broth. The jelly melts when you eat it hot. It will have a slightly thicker texture if you eat the soup cold.
Add the gefilte fish and broth to a crock pot, and cover in tomato juice. Maybe add a small can tomato sauce, for a little extra zing. If you didn't buy enough tomato juice, add water until the fish are completely covered. Add the veggies. Simmer 45 mins or until veggies are tender.
Hot, it makes a delicious soup course. Cold, it is wonderful as a stand-alone lunch.
