Preheat oven to 200 C (400 F).
Spread potatoes on a large baking sheet. Lightly spray potatoes with olive oil cooking spray, season with salt and pepper. Roast for 15 minutes.
While potatoes are roasting, cut salmon into 1-inch bites.
Prepare the maple glaze: In a large bowl, whisk together maple syrup, soy sauce, minced garlic, grated ginger, and red pepper flakes (if using).
Add the salmon to the bowl and gently stir until each piece is coated.
On a second baking sheet, arrange salmon bites. Season with salt and pepper.
Brush the salmon bites with the maple glaze.
Once the potatoes have baked for 15 min, take out of the oven. Give them a stir, push them to the side and add the uncooked asparagus.
Increase the oven temperature to 450 F (225 C). Pop both the salmon and the potato/asparagus tray back in the oven.
Bake for an additional 8-10 minutes, or until salmon is cooked through and asparagus is tender-crisp. (Note: Cooking time is reduced due to smaller salmon pieces.)
Divide the meal into containers for storage or serving. We use 600 ml glass containers.
