Tomato Soup and Toasted Cheese Sandwiches

This is what we had last night for dinner and it was delicious as always.  I got this recipe for homemade tomato soup from my sister, Jill.  It is one of Mike's favorites.  Thanks, sis!

3 quarts tomatoes- peeled and blended
1/3 C sugar
1 tsp garlic powder
1/2 tsp onion salt
1/2 tsp celery salt

Bring all ingredients to a boil then add:

1 cube butter melted with 1/2 cup flour

Cook until thick.

*Note:  This makes a lot of soup, so I usually half the recipe for just the two of us.
