Brush the bottom of the air fryer basket with vegetable oil. Preheat the air fryer to 360 degrees.
In a large bowl, mix together the chicken, rice, salsa and salt until well blended.
Place about 1/2 cup of the chicken filling in the center of each tortilla. Roll them up tightly with the ends folded in to seal in the filling.
Place the chimichangas, two at a time and seam side down, in the oiled basket. Brush the tops of the chimichangas lightly with vegetable oil.
Air fry the chimichangas for about 4 minutes at 360 degrees. Open the air fryer and use metal tongs to flip the chimichanges. Continue to air fry for another 4 minutes until the chimichangas are hot and browned.
The filling will keep in an air-tight container in the refrigerator for up to two days so the chimichangas can be prepared as needed.
Top the chimichangas with white queso cheese sauce, lettuce, tomato, sour cream and guacamole.
