Step 1

Preheat oven to 425 degrees F. Coat a large rimmed baking sheet with cooking spray.

Step 2

Toss potatoes, 1 tablespoon oil, 1/4 teaspoon salt and pepper together in a medium bowl. Transfer to the prepared pan and roast for 15 minutes.

Step 3

Meanwhile, combine chili powder, cumin, garlic powder, lime zest and the remaining 1/2 teaspoon salt in a small bowl. Place bell peppers in the medium bowl and add the remaining 1 tablespoon oil and 1/2 tablespoon of the spice mixture; toss well to coat. Coat the salmon with the remaining spice mixture.

Step 4

After 15 minutes, remove the pan from the oven. Add the peppers and stir to combine. Roast for 5 minutes. Remove from the oven; move some of the vegetables over and add the salmon to the pan. Roast until the salmon is just cooked through, 6 to 8 minutes. Serve with lime wedges.
