Preheat the oven to 400°F (200°C).
In a small bowl, mix together the harissa paste, olive oil, lemon juice, salt, and pepper.
Place the salmon fillets on a baking sheet lined with parchment paper.
Brush the harissa mixture over the salmon fillets, making sure to coat them evenly.
Bake the salmon in the preheated oven for 12-15 minutes, or until the salmon is cooked to your liking.
Garnish with fresh parsley and serve hot.
Enjoy!
