Preheat oven to 400 °F and foil and grease a baking sheet. Set it aside.
Season salmon fillets with a pinch of salt and pepper. Bake salmon 10 – 12 minutes or until fish easily flakes with a fork and internal temperature is 145 degrees.
Meanwhile, make creamy cucumber sauce. Combine sour cream and soul seasoning. Set it aside.
To shred cucumber, grate it in a cheese grater. Wrap cucumber in a paper towel and tightly squeeze excess water out of the shredded cucumber. Fold cucumber and diced tomato into sour cream.
To serve, spoon creamy cucumber sauce over salmon fillets.
