Place the tortillas on a microwave safe plate and top with a damp paper towel. Microwave for 20 seconds to make the tortillas soft and pliable.
Stir together the dijon and mayo in a small dish.
Lay 1 tortilla out on a work surface and spread lightly with the mayo-mustard mixture.
Top the mustard sauce with 2 slices of ham. Sprinkle around 1/3 cup of shredded cheese over the ham.
Fold the ends of the tortilla in and roll it up tightly. Brush lightly with melted butter and place in the air fryer basket.
Repeat with remaining ingredients.
Air fry at 400 degrees for 5-6 minutes, until the outsides are golden and the inside is hot and melty. Let sit for 1-2 minutes after cooking for the cheese to finish melting before slicing in half and serving.
Serve hot.
Notes
If you’d like these more saucy, double the mayo + dijon and either add extra to each or use it as a dip.Brushing with butter helps the tortilla to crisp up a bit as it cooks. If you’d prefer a soft tortilla, skip the butter and wrap the whole thing in foil. Cook for an extra 1-2 minutes.Make this low carb by using a low carb tortilla instead of a flour tortilla.
