Spread all the veggies on a sheet pan. Combine all sauce ingredients in a bowl. Drizzle most of the sauce over veggies (save a bit for later) and toss to coat.
Roast for 15 minutes.
Move some veggies aside and place the salmon in between. Brush the salmon with the remaining sauce. Garnish with sesame seeds.
Bake for another 12 minutes.
Broil for 3–4 minutes, depending on the thickness of the fish, until everything looks golden and perfect.
