for the chicken:
chicken breasts - 2 boneless, skinless
ham - 4 slices
swiss cheese - 4 slices
all purpose flour - 3/4 cup
salt - 1/2 tsp
pepper - 1/2 tsp
egg - 1
milk - 2 tbsp
bread crumbs - 1 cup
vegetable oil - 1 tbsp
butter - 1 tbsp

for the sauce:
butter - 2 tbsp
all purpose flour - 2 tbsp
milk - 1 cup
bouillon cube - 1, chicken flavored, crushed
salt - 1/2 tsp (optional)
dijon mustard - 1 tbsp
worcestershire sauce - 1 tsp
parmesan - 1/2 cup, finely grated

Preheat the oven to 350 F (175 C).
Slice each chicken breast in half lengthwise, making 4 thinner cutlets. Put each cutlet between two pieces of plastic wrap and flatten with a meat pounder until they are approximately 1/4" thick.
Top each cutlet with a slice of ham and cheese - then roll up tightly, tuck in the ends and secure with toothpicks.

In a shallow bowl, mix the flour, salt, and pepper together and set aside.
Whisk the egg and milk together in another small bowl and set aside as well.
Place the breadcrumbs in a third bowl.
Dip the rolled cutlets in the flour first, then the egg wash and then roll in the breadcrumbs and set on a plate.
Heat the oil and butter in a small skillet over medium heat and brown the chicken on all sides before transferring to a greased baking dish.
Bake in the oven for about 20 - 25 minutes, or until no longer pink.
While the chicken is baking, make the cream sauce:

Melt the butter in a medium saucepan over medium heat. Whisk in the flour, and continue to whisk constantly for about 1 - 2 minutes.
Slowly pour in the milk, then stir in the chicken bouillon and salt - whisk constantly over medium heat until it begins to simmer and thicken - about 5 minutes.
Remove from heat and stir in the mustard, worchestershire sauce, and parmesan until well combined and the cheese has melted.
When the chicken is cooked, remove from oven and serve drizzled with the sauce.
(remember to remove the toothpicks before serving)
