Preheat your oven to 400°F (200°C) and prepare a baking sheet with parchment paper.

Place fresh salmon fillets skin-side down on the baking sheet and slice each piece lengthwise to create a pocket.

Brush the salmon with olive oil and season with salt and pepper.

In a medium pan, heat olive oil and sauté spinach with Italian seasoning, paprika, cayenne pepper, and salt. Sauté for about 2 minutes until wilted.

Mix in the roasted red peppers, feta cheese, and grated Parmesan with the sautéed spinach.

Fill each salmon pocket with the spinach-feta mixture.

Bake the salmon for 12-17 minutes until it turns opaque and flakes easily with a fork.

Let the salmon rest for a few minutes before serving alongside your favorite sides.
