Spread butter on one side of each bread slice. Spread the other side of each slice of bread with sweet honey mustard. Top four of the bread slices (mustard side up) with 1 slice cheese, 4-oz. sliced turkey, and 2 Tbsp. well-drained sauerkraut. Place remaining cheese and bread slices atop each sandwich. Heat a large skillet over medium high heat. Grill sandwiches until browned, then turn and grill until heated through and cheese is melted. Serve with French fries and pickles. Makes 4 servings.
