• 1 ounce slice roasted chicken breast
  
• ¾ cup shredded mozzarella cheese
• 1/8 cup grated parmesan cheese
• 2 eggs, beaten
• ¼ cup milk
• 1/8 tsp freshly ground nutmeg
• 1 Tbsp butter

1)  Spread on side of bread slices with mustard.  Top remaining slices with chicken. Combine mozzarella and parmesan cheeses and mix together; sprinkle mixture evenly over chicken and close sandwiches, mustard side down.
2)  In a shallow dish or bowl combine the eggs, milk and nutmeg and mix well. Melt butter in a large skillet or on a griddle over medium heat. Dip each sandwich in egg mixture, turning to coat.
