Cut crusty rolls or French bread into ¼ inch slices.  Spread each with a bit of Ranch dressing.  Top each with a very thin slice of tomato.  Place some crumbled smoked salmon next.  Top with a few crumbles of Feta cheese, and then finish with a small slice of Provolone cheese.  Place in a hot oven for ~10 minutes or until the cheese is melted.  Serve warm.
