Preheat oven to 450 degrees F. Spray baking dish or sheet pan with cooking spray.

In large bowl, combine Brussels sprouts, broccoli, 3 Tbsp. olive oil, salt and pepper.

Transfer veggie mix to baking dish, arrange tomatoes in dish and bake for 15 minutes, stopping halfway to toss for even cooking.

Drizzle 1 Tbsp. olive oil on both sides of salmon steaks and press minced garlic onto them. Sprinkle evenly with oregano, salt and pepper.

Remove baking dish from oven; carefully move vegetables to make room for salmon steaks. Top each steak with sprig of rosemary. Bake for another 10-12 minutes or until salmon is cooked through.

Serve with lemon wedges.
