To prepare a air fryer mini peppers stuffed with cheese and sausage recipe, you will first need to prepare the pepper. Cut the bell pepper in half lengthwise and scoop out the seeds. Place the cut pepper halves in the bottom of an air-fryer basket. Fill the basket with 2 tablespoons of shredded cheddar cheese. Sprinkle with 1 tablespoon of chopped scallions and 1 teaspoon of oregano. Bake for 15 to 20 minutes or until the cheese is melted. Remove from the oven and allow to cool for 5 minutes before serving.
