Tamagoyaki Sandwich is a popular choice for Japanese Bento lunch.  Tamagoyaki, pan-fried egg, is a quick but delicious filling for sandwiches.  Just make some eggs into a thick frittata-like shape, which takes no time, sandwich the eggs with bread slices, and that’s it.  Oh – don’t forget to spread some Japanese mayo and Karashi hot mustard.  That’s the key taste of this dish.  Tangy Japanese mayonnaise and spicy mustard go very well with mild flavored cooked eggs.  To build your Bento, pack your favorite vegetables and fruits to add more nutrition along with the sandwich.  Choose colorful ones to please the eyes of your family.  There are other easy and tasty sandwich recipes in our cook book Simply Bento: Delicious Box Lunch Ideas for Healthy Portions to Go.  We have over 140 Bento recipes for both main and side dishes.  Simply Bento is available online and at book stores.
