Looking for a healthy, one-pan dinner that takes only minutes to prepare? Everyday Food editor Sarah Carey makes one just for you and shows you how to know when the salmon is perfectly cooked.
Preheat oven to 450 degrees. On a large rimmed baking sheet, toss potatoes with 1 tablespoon oil; season with salt and pepper. Roast 10 minutes.
Toss potatoes, and push to sides of sheet; place salmon in center, and season with salt and pepper. Roast until potatoes are tender and salmon is opaque throughout, 10 to 15 minutes. Transfer salmon to a plate; break into large pieces with a fork.
While salmon is cooking, whisk together vinegar, mustard, chives, and remaining 2 tablespoons oil in a large bowl; season with salt and pepper. Add arugula and potatoes; toss to combine. Top salad with salmon pieces.
