Preheat the air fryer to 400° F | 204° C

Slice a cross pattern in the middle of your bologna pieces, but not sliced to the edges. This will help the bologna to flatten out and brown all over, the cross will allow the steam to release, and help maintain the shape of the slice.

Air fry at 400° F | 204° C for 3 minutes, flip the bologna slices over, and air fry for an additional 3 minutes.

Plate with bread and sandwich fixings and enjoy!
