Place the ground pork, chopped andouille sausage, panko breadcrumbs, egg, Cajun seasoning, diced green bell pepper, chopped parsley, and minced garlic in a large bowl.
Mix everything with your hands until the ingredients are evenly combined.
Divide the mixture into four equal portions and shape each into a small loaf about 3 inches long.
Arrange the mini meatloafs in the air fryer basket, leaving space between them.
Cook in the air fryer until the outside is browned and crispy and the inside reaches a safe temperature.
Remove the meatloafs from the air fryer and let them rest for a few minutes before serving.
