Wash a 20 cm colander or sieve full of lettuce, and dry well. Rip into easy to eat pieces and put in a bowl.
Add the mentsuyu and mayonnaise and mix. Scatter nori seaweed just before eating, mix quickly and it's done.
Story Behind this Recipe
I make this salad whenever I have some leftover nori seaweed from an opened packet.
I use a 3x concentrated mentsuyu. Adjust the amount of seasonings depending on how watery the vegetables are. I often use chirimen jako (cooked, salted and semi-dried tiny sardines) instead of seaweed.
