I remember thinking as a kid whenever someone made a grilled cheese sandwich that they must be a professional cook. I think it was the flipping of the bread and perfect browning that made this sandwich seem more like a culinary feat than the peanut butter and jelly I was used to. When served with tomato soup, this simple meal felt so fancy. During my years working in culi nary design, mashing up two beloved foods into one was a trend I saw often and loved. Grilled cheese and tomato soup are an ideal pair for this mash-up. Combining that rich and creamy tomato soup texture and taste with toasted bread and cheese, this ultimate comfort food is even better in casserole form.
