Step 1

Preheat oven to 450°F.

Step 2

Stir broth, cream, garlic powder, ¼ teaspoon salt and ⅛ teaspoon pepper together in a large skillet. Add mushrooms and orzo, cover and bring to a boil over high heat. Stir in spinach, reduce heat to maintain a lively simmer, cover and cook until the orzo is tender and the sauce has reduced and thickened, 10 to 12 minutes.

Step 3

Meanwhile, brush oil on both sides of salmon pieces. Sprinkle with the remaining ¼ teaspoon each salt and pepper. Place on a baking sheet and roast until just cooked through, 8 to 10 minutes. Serve the salmon with the orzo.
