Preheat oven to 425º. Blot salmon filets with a paper towel to remove moisture.
Make the marinade: Whisk together juice of two lemons, 1 tablespoon olive oil, garlic, salt, and pepper.
Marinate the fish in it for about 10 minutes.
Combine the tomatoes, scallions, olives, 1 tablespoon olive oil, and capers in to a relish. Set aside.
Make your parchment packet: Fold a sheet of parchment paper in half and cut a half heart-like shape.
Unfold. Place fennel in a single layer on the bottom, fish in the middle, and tomato relish around and on top of the fish filet. Spoon over marinade for a sauce.
Fold parchment over fish and fold over the edges to seal. Bake for about 14 minutes, depending on how thick your filet is.
Open and serve.
For more elegant plating, remove from packet and drizzle sauce over salmon.
