I tried this recipe the other day and it was so delicious! I used two smaller dishes instead of one big one so we could eat it twice :) YUM!

Three-Cheese Macaroni
(courtesy Food Network Magazine)
Serves 6

1 large egg
1 12 oz can evaporated whole milk
pinch of cayenne pepper
pinch of freshly grated nutmeg
salt and pepper
1 1/3 c grated muenster cheese, plus 4 slices
1/2 c grated sharp cheddar cheese
1/4 c grated Parmesan cheese
1/2 head cauliflower, cut into small florets
4 c medium pasta shells

1. Whisk the egg, evaporated milk, cayenne, nutmeg and salt and pepper to taste in a bowl. Toss the grated cheeses in a separate bowl.
2.Bring a large pot of salted water to a boil. Add the cauliflower and cook until almost falling apart, about 7 minutes. Transfer with a slotted soon to a bowl. Add the pasta to the same water and cook until al dente, about 10 minutes. Drain, reserving 1/4 c cooking water. Preheat the broiler.
3. Combine the egg mixture and the grated cheeses in the empty pot and cook over medium-low heat, stirring constantly, until the cheeses melt and the sauce begins to thicken. Remove from the heat and add the cauliflower. Puree with an immersion blender until smooth and light (you can also use a regular blender). Stir in some of the reserved pasta water until creamy. Toss the pasta in the sauce; season with salt and pepper. Transfer to a shallow casserole dish and top with muenster slices. Broil until golden brown, about 5 minutes.
