Begin by patting the salmon fillets dry with a paper towel to enhance crispiness. In a small bowl, drizzle the salmon with olive oil, ensuring it's well-coated. Generously rub the Cajun seasoning and salt over the fillets.

Heat a non-stick skillet over medium-high heat for about 2 minutes. Place the seasoned salmon skin-side up in the skillet and sear for approximately 3 minutes until a golden crust forms. Carefully flip the fillets and continue cooking for an additional 2 minutes.

In a separate saucepan over medium heat, melt the butter until bubbly, then stir in honey, soy sauce, and minced garlic. Allow this mixture to simmer for 2 minutes before removing it from heat and adding fresh lemon juice.

Pour the honey butter sauce over the fillets in the skillet. Let it cook for another 3-5 minutes, spooning the sauce over the salmon frequently.

Remove the salmon from the heat, transfer to a serving plate, garnish with parsley, add lemon wedges, and sprinkle with black sesame seeds.
