Heat oven to 400°. Line a rimmed baking sheet with parchment paper. Place fennel bulb on pan and drizzle with 1 T olive oil and pinch of salt. Bake 10 min. Remove pan from oven and push fennel to one side. Add salmon and citrus slices, drizzling fish with olive oil, lemon zest, pepper and salt. Return to oven and cook 10-12 min until salmon is 140° internal temp. Remove from oven and serve immediately with salad greens and/or rice, topping fish with roasted fennel and citrus slices and drizzling with any pan juices. For variations, add some julienned shallot to pan with fennel and roast.
