Cook Noodles according to package directions. Drain and rinse with cold water. Mix with all of the other ingredients. Place in greased 9 x 13 shallow casserole.
Top with crushed corn flakes. Dot the cornflakes with pats of butter.
You can refrigerate or freeze before baking. If you choose to do either, then put the corn flakes on the top after you bring the casserole to room temperature before baking.
