The taste of the salad depends on the taste of the canned mushrooms. I adore "Bonduelle" mushrooms, but,unfortunately, I didn't have one when I was to cook. You can add as much of supplies as you like

Start with the walnuts. You need to crumble it. As I was going to pound it, I put a towel on my cutting board and placed the walnuts there to avoid its crumbs of flying away

Then I covered walnuts with the other side of the towel...

... and smashed it with the hammer.

That's it! Now you have your walnuts crumbled.

Then cut the pigeon-chest,...

...the canned mushrooms...

... and the onion.

Bring all the ingredients together

Then add the canned corn...

...and sauce it with mayonnaise.

Mix it up

That's it! Enjoy your meal :)
