Air Fryer Method:  Reheat spring rolls in the air fryer at 400 degrees F (204 degrees C) for about 3 to 4 minutes or until toasty warm.  Oven Method: Reheat spring rolls in the oven at 350 degrees F (176 degrees C) oven for 7 to 10 minutes or until toasty warm.  We do not suggest reheating in the microwave as this makes them soft and soggy.
