I bought a big piece of salmon - over 2 lbs - and although there were only 4 people eating, I didnt have any leftovers! The vegetables that I used were yellow squash, green zucchini, and tomatoes. But I would experiement with you favorite and seasonal selections (thinking of trying sweet potatoes with a sweet/tangy mustard next!). The picture is from before I put the fish in the oven.
Large filet of Salmon (mine was just over 2lbs with skin on)
Pre heat oven to 375. Place fish, skin side down, on large baking sheet. Brush top of salmon with mustard. Place thin slices of vegetables over fish, alternating for color presentation (if you have a mandolin slicer, this process will be much easier). Top with a little grated cheese and chopped dill. Bake for 30 - 35 minutes.
