Tuna Salad with Corn

Place the tuna pieces into a salad bowl (drain the liquid first). Break them up well with a fork.

Slice the onion into half-rings, then cut the half-rings in half. Pour boiling water over them and let sit for 3 minutes (this takes the edge off the onion's sharpness — you can skip this step if you prefer).

Finely chop the napa cabbage.

Add the corn, napa cabbage, and onion to the tuna. Dress with lemon juice to taste (I used 1/5 of a lemon). Season with salt, drizzle with vegetable oil, and toss everything together well.

The tuna salad is ready.
