Combine all of the ingredients except the Swiss cheese and mix well with a spoon. Let the dip sit in the refrigerator overnight.
The next day, place the dip in a greased casserole dish and sprinkle the top with Swiss cheese. Bake in a preheated 350° F oven for 30 minutes or until bubbly. If you choose to heat the dip in the microwave, cover with plastic wrap.Servings: 12
