In this recipe video, I will show you how to make Tuna Sandwich with Mayo for breakfast. This time, I created a handmade (canned) Tuna and Japanese Mayonnaise to make easy & healthy tuna sandwich. At the end, I cut the Japanese white bread into two different ways. How do you guess the flavor of handmade Tuna and Mayonnaise are like? I hope you enjoy this tutorial and give it a try!
