So, once you have made the delicious tomato soup, what are you going to serve with it? Grilled cheese, of course. A sandwich with many possibilities. The core secret to grilled cheese, I finally realized, is cooking it on a low enough setting that the outsides don't burn before the insides melt. Pretty obvious, but I'm very impatient.
Some ideas for variations:
Different bread: I like a multi-grain bread with nuts for the texture; sourdough is also good.
Different cheese: Munster is my favorite. Cream cheese can blend well with another cheese inside.
Things besides cheese to add: Mustard. I like dijon, but DOB likes yellow. Avocados, thinly sliced (by far my favorite addition). Tomatoes. Dill pickles (after the sandwich is cooked, so they stay cool and crispy).
