In a large bowl, combine the red onion with olive oil, 1 1/2 tablespoons apple cider vinegar, 1 teaspoon Dijon, garlic powder, 1/4 teaspoon parsley, 1/4 teaspoon salt and pepper to taste; let it sit about 5 minutes, so the flavor of the onion mellows.

Add the tomatoes, avocado and toss. When ready to serve, toss in chopped lettuce and cabbage, finish with the remaining 1/2 tablespoon of vinegar, taste for salt and pepper and adjust as needed.

Divide the salad in 4 bowls and top each with salmon.

Preheat the air fryer to 400°F.

Rub each fillet with olive oil and season with garlic powder, paprika, salt and pepper. Place the salmon in the air fryer and air fry for 7-9 minutes, depending on this thickness of the salmon. Please note, time may vary between air fryers.

Open basket and check for desired doneness with a fork. You can return the salmon for another 1 or 2 minutes as necessary.
