Preheat broiler. Place salmon fillets on a foil-lined pan sprayed with cooking spray (I use a Misto). Season well with salt and ground black pepper.
Place frozen vegetable in a pot with a steamer basket to steam on the stove top until tender OR cook in microwave according to the directions.
Season tender vegetables with salt, pepper, and butter. Spoon whole grain on the plate and lay fish atop. Drizzle the remaining maple mustard sauce on top of the fish and serve steamed vegetable alongside the fish. Enjoy!
This recipe can easily be doubled to serve a family of 4.
