Combine all the sauce ingredients in a small bowl.
Cut Chicken Fillet into bite-size pieces and lightly season with Salt. Heat Oil in a small frying pan and cook Chicken until golden. Remove excess Oil using paper towel if you want to do so, then pour the sauce over and keep cooking until the sauce thickens.
Half fill a bowl with Freshly Cooked Rice, place Nori, and top with Chicken and the sauce. Drizzle some Japanese Mayonnaise over, and sprinkle with finely chopped Spring Onion and Toasted Sesame Seeds. Add Boiled Egg and enjoy.
