1. 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.
2. To toast nuts, spread out in a single layer on a baking sheet. Toast in a 350° oven, stirring occasionally, for 10 to 15 minutes. Or, toast in an ungreased skillet over medium heat, stirring, until golden brown and aromatic.
