Japanese Egg Sandwich

Japanese Egg Sandwiches or Tamago Sando are the Japanese take on egg salad sandwiches. With a flavorful egg salad made with Japanese mayonnaise, sandwiched between milk bread, it has a comforting taste and texture that makes it one of the most popular sandwiches in Japan. For my take, I've taken the best parts of the sandwiches offered by Japan's three largest convenience store chains and included them to create the ultimate Japanese egg sandwich.
