Mix together soup, milk onion and pimiento. In a well-greased 8 inch square casserole, alternate potato chips, eggs, and soup mixture. Sprinkle with salt and pepper. Top with thin layer of crushed chips. Bake at 400 degrees for 20 minutes or so. (Layer like this: Chips, eggs, soup mixture, chips, eggs, soup mixture. Thin layer of chips on top)
This can be baked at a lower temperature, but needs a longer time in the oven. Keep warm until serving. Stands well. When doubling recipe, bake at 400 for at least 30 minutes.
