This corn and shrimp soup is a flavorful combination of fresh shrimp, tomatoes, and corn. A tomato-based soup is a fabulous dairy-free alternative to heavier seafood soups. Canned corn, cream-style corn, and tomatoes make the soup an easy preparation. You can put it all together quickly for a meal that will simmer for an hour before being ready to serve. The soup starts with a simple roux and uses fresh shrimp. If you use frozen shrimp, thaw them in the refrigerator just before adding them to the soup.
