Line your air fryer basket with parchment paper
Place your lime slices on top of the parchment paper, and then place your salmon on top. Season with salt and black pepper.
In a small bowl, add the butter, sweet chili sauce, brown sugar, lime juice, minced garlic, and red pepper flakes.
Brush the mixture ontop of the salmon.
Set the salmon on top of the limes, and set the temperature to 400 degrees F, air fryer setting, for 8 to 10 minutes. (The time will depend on the thickness of the salmon) For best results, brush your salmon frequently during the cooking process.
Remove the salmon, when you can easily flake it with a fork.
Add some sliced limes and diced scallions on top.
Plate, serve, and enjoy!
