Weight Watchers' Open Face Tuna and Asparagus Melt?

I have been looking for an old WW lunch recipe that had tuna on toast, topped with asparagus, a type of Swiss, mayo, and Dijon mustard or mustard seasoning sauce on it. You would then broil it until the cheese melted. My daughter remembered the recipe from when she was a child and wanted the recipe, but I can't find it now.
