Mix all ingredients except for vegetable oil. (Chop the green onion and kamaboko into small pieces.）
Heat a pan with vegetable oil, and pour in the mixture from Step 1 into the pan.
Pour the vegetable oil and roll up the egg mixture.
Once the omelette has cooked through, let it cool for a while. It'll be easier to cool this way.
This colourful omelette is good for packed lunches.
"Mai 2" made it into a big omelette.
Story Behind this Recipe
I wondered it might be delicious to add leftover kamaboko fish cakes to rolled omelettes.
Make sure not to add too much of the fillings or you won't be able to roll them up well. Just remember to adjust the amount of seasonings when preparing it with just one egg (although it will still be enough to work with).
