Croque Madame

A few days back I made Croque monsieur and everyone was all praises for it. So I thought I would make it again today with a few changes. Searching through the internet, I came to know that a Croque monsieur becomes a Croque madame when topped with a sunny side up egg. Now that indeed is hillarious!! So I made a quick change of decision and croque madame it is!!

Ingredients

1 Egg
2 Tbsp butter
2 Tbsp flour
1 1/2 cups milk
A pinch each of salt, freshly ground pepper, nutmeg, or more to taste
About 1 1/2 cups grated cheese
8 slices of multigrain bread
1 Tomato sliced.
6 sausages
Mustard as needed

Method

Preheat oven to 400°F.
Make the bechamel sauce. Melt butter in a small saucepan on low heat until it just starts to bubble. Add the flour and cook, stirring until smooth, about 2 minutes. Slowly add the milk, whisking continuously, cooking until thick. Remove from heat. Add the salt, pepper, and nutmeg. Stir in 1/4 cup of the grated cheese. Set aside.
Lay out the bread slices on a baking sheet and toast them in the oven, a few minutes each side, until lightly toasted. For extra flavor you can spread some butter on the bread slices before you toast them if you want.
Lightly brush half of the toasted slices with mustard. Add the sausage slices and tomatoes and about 1 cup of the remaining cheese. Top with the other toasted bread slices.
Pour the bechamel sauce on to the tops of the sandwiches. Sprinkle with the remaining  cheese. Place on a broiling pan. Bake in the oven for 5 minutes, then turn on the broiler and broil for an additional 3 to 5 minutes, until the cheese topping is slightly browned.  Slice it and top it with a perfect sunny side up egg and it becomes a Croque madame.
