Preheat the air fryer to 400°F (200°C) and let it warm up for about 5 minutes.Slice the Ribeye steak into bite-sized pieces and place them in a mixing bowl.
Sprinkle the steak bites with salt, black pepper, and garlic powder. Drizzle avocado oil and Worcestershire sauce over the seasoned steak, then toss everything together until evenly coated.
Once the air fryer is preheated, arrange the steak bites in a single layer in the basket, making sure they are not overcrowded. Cook in batches if necessary.
