This is perhaps my favorite "go to" luncheon recipe. They are decadent, tasty, easy and elegant enough to impress anyone's mother in law. Simply serve with fresh fruit, mimosas and a scrambled egg dish and you have a great brunch idea. So many people have asked me for the recipe and you barely need a recipe they are so easy, but don't let that secret out of the bag!
2Melt the butter over low heat in small sauce pan and add the flour all at once, stirring with a wooden spoon for two minutes.
3Slowly pour the hot milk, mustard and hot sauce into the butter/flour mixture and cook, whisking constantly, until the sauce is thickened.
4Off the heat, add the salt, pepper, nutmeg, 1/2 cup Gruyere cheese and the Parmesan and set aside.
5Halve and toast the Croissants, place the slices on 2 baking sheets and bake for 4 minutes. Turn each slice and bake for another 2 minutes until toasted
6Lightly brush half the croissant with mustard, add a slice of ham to each and sprinkle with half the remaining Gruyere. Top with another piece of toasted Croissant. Slather the tops with the cheese sauce, sprinkle with the remaining Gruyere and bake the sandwiches for 5 minutes.
7Turn on the broiler an broil for 3-5 minutes, or until the topping is bubbly and slightly browned.
*** You can also use any type of bread as a substitute for the croissant.
*** Serve with an egg dish, a fruit platter and a mimosa or orange juice and you have a beautiful and elegant brunch.
