We like to use a combination of vegetable oil & sesame oil coating the peppers. If sesame oil isn't to your liking, just use the vegetable oil, or whatever oil you prefer. If you love sesame oil, you can use all sesame oil and skip the vegetable oil. Enjoy these on their own or dipped in your favorite sauces. If you like them a little more firm and crunchy, then air fry them for a little less time.
