I am usually pretty good at organizing and following my constantly updated to-do list. But once in a while life does get overwhelmingly busy and I fail to plan ahead especially when juggling too many things at the same time. What ends up happening is I call my husband at the office asking him to meet me and the kids at a restaurant for dinner at the last minute. One of the drawbacks of not cooking dinner at home is that I don’t have “leftover” to pack for my son’s bento (lunch box) the next day. I try to save some leftover in the freezer for an emergency like these, but sometimes no luck. On those days, the easy sandwich comes in handy. Now for those living in the States, a peanut butter and jelly sandwich might be a common menu for children’s school lunch. However, both of my children always preferred hot panini sandwich than typical soft bread sandwich like these. The turning point was when we were in Japan last April. My mother loves bakeries and we often visited many local bakeries to pick up fresh bread. My children really enjoyed freshly baked bread from Japanese bakeries and they especially loved Egg Salad Sandwich, or we call it Tamago Sando (たまごサンド). Japanese sandwich usually uses crust-less white bread slices, probably from British influence. Compared to typical American egg salad sandwich, the Japanese version is very simple – there are no celery, chives or green onions. The eggs are seasoned simply with Japanese mayonnaise, salt and pepper, and sugar. Now speaking of mayonnaise, I receive several questions from some of you about Japanese mayonnaise. What’s the difference from regular kind? Well, you can read more about it here. My son loves this Egg Salad Sandwich and this menu is now one of my favorite backup bento plans. I hope you will give it a try and enjoy this simple egg salad sandwich! Check out my latest Japanese Egg Sandwich (Tamago Sando) recipe and video! Wish to learn more about Japanese cooking?
