Our local Walmart has lovely fresh Atlantic salmon. It’s silver salmon, which isn’t my favorite, but it is really good and really fresh. It comes vacuum packed in a plastic tray.
Cooking is it dead easy. It comes out beautifully moist and flavorful.
Rinse the salmon, pat dry and place skin side down on a rack over an oven pan.
Dice a couple green onions. Mix with good quality mayo (I like Sir Kensington Classic). Spread the mixture evenly over the salmon fillet. Bake at 425° for 20 minutes. If the thickest portion of the fillet flakes when a fork is inserted, it’s done.
This is fabulous stuff and it reheats well.
