Thinly slice the onions and soak in water. Drain.
Open the canned saury. Cut into 1 cm pieces and place on top of the onions (with the juice) and it's ready.
You can use julienned cabbage or lettuce instead of onions. It's delicious!
Story Behind this Recipe
I wanted to use up some cans.
There's canned saury, sardines, mackerel, etc., so use whatever's available. You can season it with soy sauce or miso if you like. It's lightly flavored and delicious. Canned food is heavily flavored, so you don't need seasonings. Kids love it if you add a bit of mayonnaise.
