Preheat air fryer to 390 F. Heat rice according to package directions.

In blender, roughly chop vegetables.

In bowl, combine vegetables, egg, cheddar cheese, garlic powder and salt. Freeze 5 minutes to slightly firm up.

Divide rice mixture into four portions and hand form into mounds.

Air-fry 8 minutes, or until golden brown. Serve with barbecue sauce or ranch dressing for dipping, if desired.
