Preheat your oven to 425°F.
Prepare the sweet potato by washing and cutting it into 1/2-inch cubes. Toss with a little olive oil, salt, and pepper, then spread on a baking sheet.
Roast the sweet potatoes in the oven for about 20-25 minutes until tender and slightly crispy on the edges.
Meanwhile, trim and halve the Brussels sprouts. Toss them with olive oil, salt, and pepper, and spread on a separate baking sheet.
Roast the Brussels sprouts in the oven for 15-20 minutes until they are crispy on the outside and tender inside, stirring halfway through.
In a small bowl, mix the maple syrup and Dijon mustard to create the glaze.
Season the salmon fillet with salt and pepper. Place it on a baking sheet lined with parchment paper.
Brush the maple-mustard glaze generously over the salmon.
Bake the salmon in the oven for about 12-15 minutes, or until the fish flakes easily with a fork.
Plate the salmon alongside the roasted sweet potatoes and crispy Brussels sprouts, and enjoy your balanced meal.
