4 slices whole-grain bread
1/8 cup low-fat honey mustard
1 crisp apple, thinly sliced
4 oz. low-fat cheddar cheese, thinly sliced
Preheat a skillet over medium heat. Lightly spread honey mustard evenly over each slice of bread. Layer apple slices and cheese over two slices of bread, using about half an apple and an ounce of cheese for each sandwich. Top both with remaining bread slices. Lightly coat the outward facing sides of the bread with butter. Grill each sandwich for 3 to 5 minutes, flipping halfway through, until cheese has melted and bread has toasted. Remove from pan and allow to cool slightly before serving.
