Steps:

• Preheat the oven to 400 degrees F.
• Sprinkle salmon with 2 teaspoons olive oil, salt, and pepper. Stir the tomatoes, shallots, 2 tablespoons of oil, lemon juice, oregano, thyme, salt and pepper in a medium bowl to blend.
• Place a salmon fillet, oiled side down, atop a sheet of foil. Wrap the ends of the foil to form a spiral shape. Spoon the tomato mixture over the salmon. Fold the sides of the foil over the fish and tomato mixture, covering completely; seal the packets closed. Place the foil packet on a heavy large baking sheet. Repeat until all of the salmon have been individually wrapped in foil and placed on the baking sheet. Bake until the salmon is just cooked through, about 25 minutes. Using a large metal spatula, transfer the foil packets to plates and serve.

Steps:

• In a large skillet over medium-high heat, heat oil. Season salmon all over with salt and pepper. When oil is shimmering but not smoking, add salmon skin side up and cook until deeply golden, about 6 minutes. Flip over and cook 2 minutes more. Transfer to a plate. Reduce heat to medium and add butter. When butter has melted, stir in garlic and cook until fragrant, about 1 minute. Add cherry tomatoes and season with salt and pepper. Cook until tomatoes are beginning to burst, then add spinach. Cook until spinach is beginning to wilt. Stir in heavy cream, Parmesan, and herbs and bring mixture to a simmer. Reduce heat to low and simmer until sauce is slightly reduced, about 3 minutes. Return salmon back to skillet and spoon over sauce. Simmer until salmon is cooked through, about 3 minutes more. Garnish with more herbs and squeeze lemon on top before serving.
