I found this copycat recipe from a website. It is soooo easy and incredibly good! I've made this several times for my family and friends and they just love them. They think these are better than the ones served in the restaurant! I add extra cheese on top (maybe that's the key) ; ) Hope you enjoy!
This tuna salad served atop toasted sourdough bread makes a satisfying lunch or dinner. The beans, tuna and walnuts offer interesting contrasts in texture, while providing fiber, protein and healthy fat.
