Step 1

In a large, heavy bottomed saucepan, melt the butter and slowly whisk in the flour until a thick paste or roux forms.

Step 2

Continue to cook roux for 2 minutes over medium-low heat, stirring frequently. Add the half and half to the pan and whisk until smooth.

Step 3

Cook over medium heat until the mixture begins to simmer, about 2-3 minutes. Remove the sauce from the heat and slowly stir in the cheese until the sauce is smooth. Stir in the nutmeg, salt and pepper to taste.

Step 4

For each sandwich, place one slice of toast in an oven safe dish and cover with half the turkey. Top with two slices of Roma tomato and cover with half of the sauce. Sprinkle the top with additional cheese and place under a broiler until the cheese begins to brown and bubble.

Step 5

Remove fromn the oven and top with two pieces of crispy bacon. Sprinkle with parsley and serve immediately.
