Day After Christmas Soup

...otherwise known as Beef Vegetable Soup. :-)

Leftover prime rib carcass--trimmed of fat, bones separated, meat cut into chunks
1-2 onions, chopped
3-4 carrots, chopped
2-3 celery ribs, chopped
1 zucchini, chopped
2 cloves garlic, minced
1 can black beans, drained and rinsed
1/2-1 can diced tomatoes
1 can corn, optional
1 potato, diced, optional
Leftover au jus
Beef stock--homemade if possible; low sodium, aseptic pkg if store bought
Fresh parsley, minced
Salt and pepper to taste

In a medium sized stockpot, heat 1-2 T oil and saute onions, carrots and celery until onion are tender. Add meat and other vegetables, then cover with beef stock and au jus by 2". Bring to a simmer and let cook until all flavors meld together, at least one hour. During the last 10 minutes, adjust seasonings and add fresh parsley.

Before serving, remove bones and let cool. Serve bones to an eager dog. :-) Serve soup to the rest of the family with salad and bread.
