1 small package mushroom
1 onion. chopped
3 tomatoes, chopped
Saute the onions in a pan with oil. Add the tomatoes. Cook for 5 minutes. Add the mushroom, salt and pepper cook for another 5 minutes, and turn off the stove. Set aside.
1 big salmon fillet (the ones from costco/ sams club) or arrange a couple of salmon fillet together. Butterfly the parts of the salmon that are too thick. Clean with water and pat dry
1/3 of a jar of mayonnaise

In a big tray or a deep baking pan or a casserole dish, arrange the salmon fillets that it will cover the whole area.
Poke holes on them with a fork. Sprinkle a little salt. Spread the mayonnaise evenly on top of salmon ( I like lots of this!). Pour the Kikkoman soy sauce evenly. And then the lemon juice.
Then, add the Topping of mushrooms and tomatoes evenly. Sprinkle some pepper. Wrap it nice and tight with aluminium foil and bake at 375 for 25-30 minutes.
