Notes
For added heat, feel free to sprinkle red pepper flakes on top when serving.How to turn this into a freezer meal:
Place flank steak, soy sauce, water, brown sugar, and ginger into a gallon-sized freezer bag. Place freezer bag into freezer and it will last up to 90 days.
When ready to use, dump ingredients from bag into Instant Pot and add 1/2 cup water in with the frozen food. Place the lid on top, move the valve to SEALING, and press the MANUAL button. Set timer for 25 minutes and do a NATURAL RELEASE when the timer is done – I even like to let it sit in the Instant Pot for a few hours so that it falls apart so easily. Follow the rest of the instructions as written.
