Prep your instant pot/air fryer with 1 cup of water (200ml)
Place 4 eggs in the wire rack and lower them in to the water. If using the air fryer, place them on the grill rack.
Make sure the lid is set to "Sealing" and close the list. Switch on the instant pot and pressure cook as per the manual for 5 minutes.If using the air fryer, switch the vent round to seal. Make sure to use Low pressure mode (it will default to High so make sure to change it from this). While this is cooking, put your bread in the toaster.
Once the timer is done, release the pressure then remove the lid - being careful of the steam. To stop the eggs cooking further, you can place them in cold water for 1 minute.
Serve up with the toast - cut into soldiers of course. Season according to your taste and enjoy.
