Put sliced peaches,juice and all, in a 9x13 pan. Top w/dry cake mix w/out lumps. Pour melted butter all over the top and sprinkle the nuts over the top. Bake @ 350* until tests done, about 20-30 minutes. But, keep eye on it. Let cool and serve with ice cream or a dollop of cool whip/whip cream. Delicious!!
