Mix ground meat with salt, pepper, garlic powder and onion powder in a bowl.
Mix them well and form four patties.
Make sure to maintain the thickness of the patties by about half an inch.
Make sure to press the middle of the patty with your thumb so that the patty does not bump up from the center.
Now brush the patties with some barbecue sauce.
Now you have to preheat the air fryer up to 370 degrees Fahrenheit temperature.
Put the patties in an air fryer basket.
Make sure to put them in a single layer.
Now cook for up to 6 minutes.
Flip the burger patties and cook for an additional 3 to 5 minutes or until you notice the internal temperature of the beef turns 160 degrees Fahrenheit.
You can also add cheese if you want and cook for one more minute.
Now you have to assemble the burger.
What you have to do is take the lower part of the bun and put some ketchup or mayonnaise on it if you want.
Then place salad leaves and tomato pieces and then put cooked beef patties on top of veggies.
Now place a cheese slice if you want and cover it with another top half of the bun.
