Creamy Tomato Soup with Cheese Toasties

To keep our tomato soup a one-pot operation (and avoid splattering scalding hot liquid), we purée the mixture with an immersion blender, which gets the job done. For an extra-smooth texture, though, feel free to use a regular blender. Want to keep it vegan? (Well, the soup, that is.) Omit the sour cream and drizzle with a couple of extra tablespoons of olive oil at the end.
