creamy tomato soup

I'm not sure where I got this recipe, but it's one of my favorites -- which says a lot since I'm not a big soup person.  If you do make this, my one piece of advice is:  do not freeze it.

Creamy Tomato Soup
Serves 6-8

1 med. onion, chopped
2 Tbsp. butter
2 14.5 oz cans diced tomatoes, undrained
2 cans of condensed tomato soup
1.5 C. milk
1 tsp. sugar
1/2 - 1 tsp. basil
1/2 - 1 tsp. paprika
1/8 - 1/4 tsp. garlic powder
8 oz. cream cheese, cubed

In soup pot, saute onion in butter.  Stir in all ingredients except the cream cheese.  Bring to a boil.  Reduce heat; cover and simmer for 10 minutes.  Whisk in cream cheese until melted.
