Preheat your oven to 350°F (175°C) and prepare a baking sheet with parchment paper.

Drizzle 1 tablespoon of olive oil over each salmon fillet, rub it in and season with salt, pepper, smoked paprika, and Cajun seasoning.

Create a slit in the center of each salmon fillet without cutting all the way through.

In a mixing bowl, combine spinach, Boursin cheese, diced jalapeno, lump crab meat, Parmesan cheese, and minced garlic. Mix thoroughly and season with salt and pepper.

In another bowl, season shrimp with remaining olive oil and seasonings, mixing until coated.

Stuff each salmon slit with the crab mixture, then top with the seasoned shrimp, and optionally pour melted butter over them.

Bake the stuffed salmon on the prepared sheet for 15-17 minutes until opaque and flaky.

Serve hot with fresh lemon wedges.
