Cook pasta according to package directions. Rinse and drain.
In a medium bowl, whisk evaporated milk, dressing and eggs together until smooth. Fold in the cheese. Add the cooked pasta and mix well. Spoon pasta mixture into an oiled 1½-quart casserole. In a bowl, combine bread crumbs and melted butter. Sprinkle on top of pasta. Bake for 20 to 25 minutes until the top is nicely browned and heated through.
