- Salmon:
- 4 (6 ounce) salmon fillets
- 2 teaspoons seafood seasoning (such as Old Bay®), or to taste
- salt and ground black pepper to taste
- 1/2 cup freshly squeezed lemon juice
- 4 teaspoons extra-virgin olive oil, or to taste
- 4 teaspoons white wine, or to taste

- 2 tablespoons Dijon mustard
- 2 tablespoons extra-virgin olive oil
- 2 tablespoons lemon zest
- 2 tablespoons chopped fresh rosemary
- 4 cloves garlic, minced
- 1/4 teaspoon salt
- 1/4 teaspoon ground black pepper
- Preheat an outdoor grill for high heat, and lightly oil the grate.
- Season salmon with seafood seasoning, salt, and black pepper. Arrange salmon in the center of a large piece of aluminum foil; add lemon juice, 4 teaspoons olive oil, and white wine. Top each fillet with 2 lemon slices, capers, and a fresh rosemary sprig. Fold three of the sides of the foil toward the middle, creating a foil bag.
