Sometimes a recipe comes to me based on one single ingredient.  In this case it was a gorgeous Kimmelweck roll in the case at the bakery.  I couldn’t wait to get home and make tuna melts for lunch.  I promptly proceeded to burn the bun.  With all other ingredients gathered I turned to my freezer to find the tail end of a pack of Party Rye.  And that is how the Tuna Melt Grilled Cheese Slider was born.
