Try to cut the chicken into pieces that are the same size, this will ensure that they cook evenly.
When cooking the chicken in a cast iron skillet, add them to the skillet and let them cook for 1 minute without disturbing, this will give them a golden color.
Feel free to add more vegetables to the stir fry, you can also add water chestnuts, shredded cabbage, or even fresh herbs if you like.
If the sauce thickens too quickly, loosen it up with a splash of water. If it doesn’t thicken to the desired consistency, add 1 teaspoon of cornstarch mixed with 1 teaspoon of water. Keep in mind that cornstarch must be cooked to 203°F/95°C before it starts thickening.
Store the leftovers in an airtight container in the fridge for up to 3 days. Reheat in a skillet with a splash of water until just warmed through.
