In a large pot, heat the milk and add the 3/4 of each cheese. Stir in the pasta and soybeans. Check for seasoning. Place in ovenproof casserole and top with remaining cheese. This will hide the protein packed green things. Broil on high until bubbly brown. If placing in the oven from a cooled or cold state, then heat in the oven at 350 degrees for 15 minutes before broiling.
