I am love with this new Cooking Channel show " Little Paris Kitchen" with Rachael Khoo. She made this awesome breakfast Croque Madame Muffins. I made them this morning with some fried potatoes for our "Special Breakfast Day." I think this would make the perfect Christmas morning meal! I made mine with regular store bought bread and instead of making a standard Bechemel white sauce, I made mine with cheddar cheese. It's the same sauce I make for my mac and cheese.
In a sauce pan mix 2 TBSP butter and flour. Mix with a whisk over medium low heat until it becomes light brown. Add 1 cup milk (we use skim), and bring just to under a boil. Stir to get out all the lumps. Also, if you let the sauce sit it will get lumps. Add 1/4 cup grated cheese *I used cheddar. Mix with the whisk until the cheese is melted. You want the sauce to thicken. Remove from the heat and add a pinch of Dijon mustard and nutmeg, salt, and pepper.
