French Grilled Ham and Cheese

I got this recipe from the Rachel Ray show awhile back and it's been one of my family's favorites.

Get ready for some awesomeness! 

Ingredients~
Thick Sliced French Bread  (from bakery is extra nice)
Good quality thin sliced deli ham (I like applewood ham)
Baby swiss cheese
2 T butter
flour
milk
Dijon mustard
salt
pepper
nutmeg

Make Spread~
Melt 2 TBS butter in skillet, add enough flour for a thickening and then a splash of milk, stirring quickly so there are no lumps and you get a smooth consistency.  Add a pinch of salt and a dash of pepper with another pinch of nutmeg.  Then stir in a dollop of Dijon mustard.  Mix well.

Make Grilled Sandwiches~
Butter outsides of french bread slices.  Lay butter side down on grill or skillet and add some spread.  Layer on a small amount of ham ( I use about 3 thin slices) and a piece of baby swiss cheese.  Turn grill or burner on low and grill slowly til outsides are brown and crispy and insides are warm with cheese melted and gooey
