1Layer the chicken, ham, and cheese in a baking pan. Cover with soup and then bread crumbs. Melt the butter and drizzle it over the casserole. Drizzle the water over the casserole also (keeping in mind that you may need a little more or less water, depending on how dry the overall dish looks once the butter has been drizzled on it). Bake for 1-1 1/2 hours at 400 degrees.
