Stir all the breading ingredients together in a shallow bowl and set it aside.
Preheat the air fryer to 400 °F
Squeeze as much water as you possibly can out of the thawed spinach (alternatively, you could also cook some fresh spinach until it's very wilted)
Heat the olive oil in a skillet over medium heat. Cook the garlic for one minute until fragrant. Add the 2 tablespoons of broth, the spinach and green onions to the skillet. Cook for another 2 or 3 minutes until the onions are soft.
Pound the chicken breast very thin, to about ¼-inch thickness.
Cut the flattened chicken breast into 4 equal pieces (you'll be rolling this up like a jelly-roll, so keep this in mind when deciding how you want to divide your chicken breast up)
Lay 2 slices of ham and 1 ounce of swiss cheese over each piece of chicken. Spoon ¼ of the spinach mixture on top, and roll the chicken up like a jelly roll. Use toothpicks to secure the chicken and hold it shut.
Roll each chicken roll in the breading mixture, shaking off the excess. Next, transfer each chicken roll to the basket of the air fryer.
Spritz the chicken lightly with nonstick spray before cooking (this will help the breading brown up)
Cook the chicken in the air fryer for 15 to 20 minutes. The chicken is done when a thermometer registers an internal temperature of 165 °F
