Forgot to take a picture before we dug in, but our household really loves this. We used half a block of light cream cheese instead of a full block, since the Kewpie mayo was doing a lot already for the creaminess. Salmon with skin on, nice and crispy, also didn't need any seasonings.
This is a nice comfort food that isn't quite as heavy as typical American comfort food goes. We put a big square on our plates, then scooped bite sized pieces into a nori snack sheet with a fork. Unfortunately we couldn't get masago at the white people store, so we had to do without. Turned out great nonetheless!
