Creating the Roasted Salmon & Potatoes Plate is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Potatoes: In a large bowl, combine the halved baby potatoes with 2 tablespoons of olive oil, garlic powder, onion powder, paprika, salt, and pepper. Toss well to ensure the potatoes are evenly coated.
3. Arrange on Baking Sheet: Spread the seasoned potatoes on a large baking sheet in a single layer. Roast in the preheated oven for 15 minutes.
4. Prepare the Salmon: While the potatoes are roasting, season the salmon fillets with the remaining tablespoon of olive oil, salt, and pepper.
5. Add Salmon to the Baking Sheet: After 15 minutes, remove the baking sheet from the oven. Push the potatoes to one side and place the salmon fillets on the other side.
6. Continue Roasting: Return the baking sheet to the oven and roast for an additional 10-15 minutes, or until the salmon is cooked through and flakes easily with a fork.
7. Garnish: Once cooked, remove the baking sheet from the oven. Sprinkle fresh parsley over the salmon and potatoes for added flavor and color.
8. Serve: Let the dish cool for about 5 minutes before transferring it to plates. Serve with lemon wedges on the side for squeezing over the salmon.
