Mackerel can sandwich
Even children who don't like fish can enjoy it.
Make sure to remove the spiciness from the onions.
Thinly slice the onion perpendicular to the grain, soak in water for a few minutes, then drain well
Mix the room temperature butter and mustard thoroughly and spread generously on the surface of the bread
Spread butter on top, add a moderate amount of mayonnaise, and top with lettuce
Next, place the shredded canned boiled mackerel and blanched onion on three of the six slices of bread
Place the canned mackerel on top of the other piece of bread, cover with a cheesecloth, press lightly with your hands, and let it sit for a few minutes
Remove the cloth and cut into bite-sized pieces
