In a 2 quart buttered baking dish, layer cooked noodles with grated cheese (2 layers). You may not need to use all of the noodles. If you use too many it can make the recipe turn out too dry.

Mix eggs, mayo, mustard, milk, salt, and pepper. Pour over noodles and cheese (should not be dry). Dot with butter.

Bake at 350F for 45 minutes or until done. Should be golden and sizzling!
