Combine all seasoning ingredients in a small bowl.
Salmon
Pat the salmon dry and season generously on both sides with the seasoning blend.
Heat the oil in a non-stick pan over medium-high heat. Add the salmon skin-side down, lower the heat to medium, and use a spatula to press the salmon down for about 10 seconds.
Cook for about 5-6 minutes, flip, then cook for another 2-3 minutes until cooked through.
Avocado Salsa
Add all avocado salsa ingredients to a large bowl and toss until evenly combined. Taste the salsa and add additional lime juice, salt, or pepper as needed.
Divide the salmon and avocado salsa onto plates to serve. Squeeze with additional lime juice as desired.
