Directions

1. Preheat oven to 375 degrees. Place tomatoes on a rimmed baking sheet; drizzle with 2 teaspoons olive oil and season with salt and pepper. Transfer to oven and roast until tomatoes begin to split, about 8 minutes. Remove from oven and let cool slightly.
2. Meanwhile, using a sharp knife, score skin side of salmon fillets; season with salt and pepper. Place salmon, skin-side down in a large, heavy-bottomed nonstick skillet. Place skillet over medium-low heat. Increase heat to high and cook until skin is golden brown, 2 to 3 minutes. Turn salmon and continue cooking until salmon is just pink in the center, 1 to 2 minutes more.
3. In a medium bowl, whisk together lime juice, grapeseed oil, and remaining 1/4 cup olive oil. Season with salt and pepper. Place a 3-inch round cutter in the center of a serving plate and mound a quarter of the lettuce leaves into cutter. Remove cutter and repeat process on three more serving plates.
4. Top each salad with a piece of salmon and some of the tomatoes; drizzle with lime-juice mixture. Serve immediately.
