01 - Warm tortillas until flexible. Divide mayonnaise and mustard among them, then add two slices ready-to-eat chicken ham and one slice Swiss to each.
02 - Fold sides inward, roll securely and brush with melted butter. Place seam-side down in an uncrowded basket.
03 - Air-fry at 380°F for about five minutes, extending as needed until the center is steaming hot and reaches 165°F. Shield or lower heat if the wrapper browns first.
04 - Rest briefly and cut with support under the seam. Follow any additional heating directions on the meat package.
