Toss broccoli florets, grape tomatoes, carrot pieces, 2 tsp. olive oil, and a pinch of salt and pepper on other side of baking sheet. Roast 10-14 minutes, or until vegetables are softened and salmon is flaky (minimum internal temperature should be at least 145 degrees). Remove from oven. Use half of lemon pepper seasoning to top both pieces of salmon, then drizzle each with 1 tsp. lemon juice.
