If you don't have a toaster for work, you can pop them in prior to leaving and wrap in foil to keep warm.
You can also air fry these wraps when reheating. Cook for 3-4 minutes at 180 degrees Celsius, turning part way through. Alternatively, pan fry until warm throughout.

I used Turkey rashers here but you can use pork bacon too. Just make sure to wrap tightly enough to slide into the toaster.

PLEASE be careful when removing from a toaster. I know most people are aware to not put anything inside whilst it's turned on but I just want to be sure.
