Preheat your oven to 400°F (200°C). Slice salmon fillets lengthwise to create a pocket.

Drizzle olive oil over salmon and season with salt and pepper.

In a large sauté pan, add remaining olive oil, then add spinach with Italian seasoning and paprika. Sauté for 3-4 minutes until wilted.

Remove from heat, stir in roasted red peppers, crumbled feta, and grated Parmesan until well combined.

Stuff the salmon pockets with the spinach filling, pressing slightly to secure.

Place stuffed salmon on a lined baking sheet and bake for 12-17 minutes until opaque and cooked through.
