Preheat oven to 350°.
Cook noodles following package directions; drain. Cook broccoli just until tender.
In a saucepan over low heat, melt butter; blend in flour, salt, prepared mustard, and pepper. Stir until smooth and bubbly. Gradually add milk, stirring until thickened; remove from heat and stir in cheese until melted. Dice broccoli stalks; leave flowerets intact. In an 8-inch square baking dish, arrange noodles, broccoli stems, and turkey; pour cheese sauce over all. Arrange the flowerets over the top, pressing down a bit. Sprinkle with almonds. Bake for about 15 minutes, or until hot and bubbly.
Turkey casserole serves 4.
