Baked Steak Soup

This recipe calls for putting this in the oven at 250 for 6-7 hours.
I put it in the crockpot on low for about 6 hours,
then turned it to high for 2 hours.

3 large carrots, peeled and sliced
8 oz mushrooms, sliced

2 large potatoes, peeled and diced
28 oz. can tomatoes, crushed with juice
10 1/2 oz. can beef broth
1/4 cup white wine (you can use water)
4 Tbsp. tapioca
1 Tbsp. brown sugar
1/2 cup bread crumbs
1 bay leaf
salt and pepper to taste
Mix,
cover and put in oven at 250 degrees for 6-7 hours.
