In a microwave-safe bowl, melt the butter, then whisk in the Worcestershire Sauce, Seasoned Salt, Garlic Powder, and Onion Powder.

Spray the foil with olive oil cooking spray and evenly pour the mix into the air fryer, right on top of the foil.
Evenly pour the butter mixture over the snack mix.
Using the air fryer, cook at 350* for 3 minutes, stir it up, and then cook for an additional 3-4 minutes until your desired doneness.
