Begin by preparing a garlic-infused butter mixture. In a bowl, combine the melted butter with the pressed garlic and a sprinkle of chopped parsley. Set this mixture aside.
Prepare the pork tenderloin: Cut the pork tenderloin into strips and place them in the basket of the air fryer. Add a touch of oil, a pinch of salt, and black pepper. Set the air fryer to 200ºC with the "Air Fry" function for 10 minutes.
Garlic bread with butter: While the pork is cooking, spread the garlic butter mixture on the slices of bread. Place the buttered bread in the basket of the air fryer and set the air fryer to 200ºC with the "Broil" or "AirFry" function for 3-4 minutes, until the bread is golden brown.
Assemble and melt the cheese: Once the pork is done, remove it from the air fryer and place it on the garlic bread. Sprinkle grated mozzarella over the pork. Set the air fryer to 200ºC with the "Air Fry" function for an additional 3 minutes or until the cheese is melted. Sprinkle the toasts with freshly ground pepper and garnish with a bit more chopped parsley. Enjoy your delicious air fryer pork tenderloin and Brie toasts!
