Squeeze the water from the soy curls with tongs, then place the curls in a dry bowl. Add the chicken salt and mix well. Give the air fryer basket a couple of sprays of avocado oil. Put half the soy curls in the air fryer basket and cook on 390 degrees for 8 minutes, removing the basket a couple of times to shake. Meanwhile, put Frank’s sauce and the butter in a saucepan and heat on medium-low. Once the soy curls are done, remove them from the air fryer basket and place them in a bowl, then add 1/2 of the Frank’s sauce to the cooked curls and stir until well coated. Put the sauced curls back in the air fryer basket and cook at 390 degrees for an additional 6-8 minutes, shaking the basket a couple times. Once done, remove the curls from the basket and sit aside. Repeat the process with the remaining half of the soy curls.
