Let's start with the tomato soup. Until I made this version, I had never been able to get past bite #2 of a bowl of tomato soup. Then I made this, at the request of a husband who's very fond of soup with his grilled cheese.
Creamy Tomato Soup
1 medium onion
2 Tbsp butter
2 cans diced tomatoes
2 cans tomato soup or cartons of soup (Aldi sells a Roasted Red Pepper Tomato Soup that's excellent here)
1 1/2 cups milk
1 tsp sugar
1 tsp dried basil
1 tsp paprika
1/4 tsp garlic powder
1 8 oz package cream cheese, cubed
Saute onions in butter. Stir in tomatoes, soup, milk, and spices. Bring to a boil. Reduce heat, cover, and simmer ten minutes. Stir in cheese until melted (or "melty").
Now let's move on to the sandwich portion of our meal. For tips on your grilled-cheese technique, check out The Kitchn. For a recipe that takes some special ingredients but will knock your socks off, try Ina Garten's Ultimate Grilled Cheese (omit the bacon for a meatless sandwich). And finally, an option for your cheese-averse child (don't laugh, and don't worry - I grew out of it): a grilled peanut butter sandwich is a great alternative.
