I call this "Kitchen Sink" because it really will absorb just about anything you have on hand -- be creative! Just about any cooked meat or sausage works, and you can add extra vegies or leftover potatoes (cut bite-size). Any choice of cheese works, too -- just use your imagination to choose seasoning accordingly. Depending on what cheese and meat is used, this can also be very low calorie. And so EASY. Sometimes I combine the meat with everything else, then serve at room temperature in small squares as finger food at a party or picnic.
