Classic cheese fondue. Cheese and white wine are the center pieces of the dish. Beer or broth can be substituted for another occasion. The list of fondue dippers is endless. I've included a substantial list, but feel free to try anything that goes with cheese.
You can also use a crock pot. For that method mix the cheese with the cornstarch and coat well. Then simply add all of the ingredients to the pot and let it heat slowly, stirring often.
