Found this recipe in "The Metro St. Louis Guide to Smart Parenting" as a kid-friendly healthy recipe. Very simple and very tasty! The sauce rEALLY makes the recipe! The soy and panko give a nice twist to the familiar boring tuna cakes of yesteryear. Can be used as a main dish or as an appetizer. NOTE: Due to the concensus of reviewers, I have decreased the original 1/4 cup soy sauce to 1.5 tablespoons.
