Preheat oven to 400.
Toss the brussels sprouts with the olive oil directly on the baking tray, then season with sea salt. Flip brussels sprouts so all cut sides are flat on the tray for maximum roasty goodness. Move brussels sprouts towards the ends of the baking tray to make room for the salmon fillet.
Coat the salmon fillet all over in a bit of additional olive oil, then place skin side down on the baking tray. Generously sprinkle the bagel blend seasoning on top of the salmon, patting it down so it adheres nicely. Don't be afraid to totally pack it on.
Place the tray in the oven, and roast for 15 minutes.
Remove from the oven and allow to cool for a few minutes briefly, then serve. Eat the salmon's skin if you desire--it's awesome.
Serve with sliced lemon wedges.
