In a large bowl, toss potatoes with 1 tablespoon of olive oil, garlic powder, paprika, salt, and pepper. Spread them in a single layer on a large baking sheet.
Roast potatoes for 15 minutes.
While potatoes roast, toss broccoli, bell pepper, and red onion with the remaining 2 tablespoons of olive oil, salt, and pepper.
Add the seasoned vegetables to the baking sheet with the potatoes.
Place the salmon fillet on the baking sheet among the vegetables. If using a glaze, brush it over the salmon.
Return the baking sheet to the oven and roast for another 12-15 minutes, or until the salmon is cooked through and flakes easily with a fork, and the vegetables are tender and slightly caramelized.
Serve immediately.
Notes
For a honey-garlic glaze, whisk together honey, soy sauce, and minced garlic. Brush onto salmon during the last 10 minutes of cooking.
Ensure vegetables are cut into similar sizes for even roasting.
Adjust cooking time based on the thickness of your salmon fillet.
