In a medium saucepan over medium heat, mix the meat, beans, and green peppers together, stirring occasionally.
Warm-up your tortillas in the microwave for 30 seconds so they are warm and pliable. This makes it easier to roll the filling inside. Place half of the filling mixture into the middle of the tortilla, draining as much liquid as you can before you put it on. Wrap the tortilla, nice and tight, just like a burrito.
Spray the air fryer basket with non-stick and then place the chimichangas inside. Spray the top of them with non-stick spray and cook them at 350°F for 8 minutes. Flip, spray again, and cook for another 4 minutes on the other side. At this point, your chimichangas should be done but if you want them a little more brown, you can cook on the first side for a few more minutes.
