In a bowl or plastic bag, toss wings in olive oil. This wont coat wings much, it is just a little oil to help crisp the wings more.
Generously salt and pepper wings.
Place wings in air fryer basket so they aren't crowding each other.
Fry in air fryer for 25 minutes at 375 degrees, pulling out basket to quickly shake wings to rotate them every 5 minutes or so.
After 25 minutes, shake wings again, and then fry at 400 for 6 minutes to make wings extra crunchy.
As wings are in final fry, melt butter in small pot on stovetop, adding in nandos sauce when it is melted.
Stir well to mix, remove from heat.
Add chicken wings when fried to a large bowl.
Drizzle sauce over wings, stirring them to mix sauce evenly.
Toss wings in sauce until evenly coated.
Plate and serve immediately.
