Sprinkle pepper over the salmon fillet then set aside.

Preheat a pan over medium heat then pour olive oil into it.

Once it is hot, put the salmon in the pan and sear it for approximately 4 minutes then flip it.

Sear the other side of the salmon and cook until it is completely done and both sides of the salmon are cooked.

Remove the cooked salmon from the pan and place on a plate.

Next, stir in mushroom then sauté with the remaining olive oil.

Once the mushroom is wilted, stir in chopped spinach and tomatoes then toss with balsamic vinegar.

Transfer the vegetables to a serving dish then put the cooked salmon on top.

Serve and enjoy.
