This is one of my two very favorite chicken recipes! [J adds: 'The other is 'Chicken Poppyseed Casserole.']
In a pie plate or shallow bowl, combine butter, mustard, w.sauce, and salt. In a plastic bag, combine bread crumbs and cheese. Dip chicken in butter mixture, then shake in crumb mixture. Place in ungreased 9x13 baking pan. Drizzle with any leftover butter mixture. Bake at 350 degrees for 40-45 minutes.
