Does anyone remember a show called Ham on the Street when the Food network first became popular? One of the episodes was about making a variety of grilled cheese sandwiches and asking people on the street to try them. One of the most popular sandwiches had strawberry jam and Havarti cheese! I don't remember what kind of bread they used, but I tried it with whole wheat bread and it was very messy but very delicious! (And very fattening!)
