How to Make It
Preheat oven to 400ºF. Season salmon with salt and pepper. Wrap each fillet with a slice of bacon; secure with a toothpick. Place a large skillet over high heat until very hot, add 1 Tbsp. oil and heat until just smoking. Add salmon; cook until bacon is crisp, about 3 minutes. Carefully turn salmon over and cook 2 minutes longer. Transfer skillet to oven and roast salmon, 2 minutes for medium or 4 for well done.
Toss arugula with juice and 1 Tbsp. oil; season with salt and pepper. Divide among 4 plates. Remove toothpicks from salmon, leaving bacon in place. Place salmon on top of arugula. Serve immediately.
