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.
