Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper for easy cleanup.
In a small bowl, whisk together 2. 0 tbsp (30ml) coconut oil and 1. 0 tbsp (15g / 0.53 oz) tandoori seasoning until a paste forms.
Coat the 25. 0 oz (708g) of salmon pieces evenly with the spice mixture and place them on the prepared baking sheet.
Bake the salmon in the center of the oven for 20. 0 minutes, or until the internal temperature reaches 145°F (63°C) and the fish flakes easily with a fork.
While the fish bakes, prepare the cooling sauce by mixing the 0. 5 (150g / 5.3 oz) shredded cucumber, 1. 25 cups (285g / 10.1 oz) sour cream, 2. 0 cloves (6g / 0.21 oz) minced garlic, 0. 5 (15ml) lime juice, and a pinch of salt in a medium bowl.
Drizzle the salad with the juice of 1. 0 (30ml / 1 fl oz) lime and toss gently to ensure the avocado is coated to prevent browning.
To serve, portion the crispy salad onto four plates, place one piece of the baked salmon on top, and finish with a generous dollop of the cucumber sauce.
Pat the Salmon Dry: Before applying the oil and spice mixture, use a paper towel to pat the salmon fillets completely dry. This helps the tandoori spices adhere better and ensures the exterior gets a beautiful sear in the oven rather than steaming.
Don't Overbake: Salmon continues to cook for a few minutes after being removed from the oven. Aim for an internal temperature of 140°F (60°C); it will reach the food-safe 145°F (63°C) while resting, keeping the fish moist and buttery.
