Cut out 3 or 4 rounds from each slice of bread using a 2" round cutter. On a baking sheet toast the rounds under a preheated broiler, turning once until golden. In a bowl, combine the apple, cheddar cheese, mayonnaise, honey, mustard, caraway seeds and pepper. Spread each toast with a scant teaspoon and broil for approximately 2 minutes. Makes approximately 28 pieces, serving 6 to 8 people.
