Mix the chicken, olives, eggs, onion, celery and mayo together. Cream the butter and kraft cheese together. Butter a 9x13-inch casserole. Put down slices of bread, with the crusts cut off, to cover the surface area of the casserole dish. Spread the chicken mixture all over the bread. Cover again with slices of bread, then spread a generous layer of the cheese mixture. Refrigerate overnight, then allow to reach room temperature. Bake at 400° for 20 minutes, uncovered. Saute the fresh, sliced mushrooms. Boil the can of cream of mushroom soup with a little extra water in a pan and boil. Add the mushrooms and pour over the top of the sandwiches.
