It's hard to say. I like both but when I think about "sandwich", my childhood memory with Mama made Japanese style sandwiches comes in my mind 😊

My all-time favorite sandwich is Tamago-Sando 😍I have to buy them at least once a day at 7/11 every time I visit Japan hehe

I'm too much into Onigiris at a convenience store when I'm back in Japan as they are so expensive in Germany. I must try Tamago Sando next time 😁
