Unroll dough into 6 wedges on lightly floured surface. Put one slice of ham on widest end of each dough wedge and top with slice of cheese, tucking in any that hangs over the edges of the dough. Roll the dough tightly into crescent shape.
Place rolls on cookie sheet and bake until golden brown, about 12 minutes. Remove from oven and brush tops with softened butter. Serve immediately.
