Place the steak in a bowl and cover with the spices and parsley.
In a small sauce pan, at medium heat, combine all the ingredients except the lemon juice.
Mix the sauce gently with a whisk or a wooden spoon for about 5 minutes until it blends together.
Take the peanut sauce off the stove, and mix in the lemon juice.
Preheat the air fryer for 5 minutes at 375°F (190°C).
Spray the air frybasket with some vegetable oil.
Place the steak bites in the air fryer basket for 4 minutes, shaking and rotating them every 2 minutes or so. (Don't overcrowd the basket, lay the steak bites in a single layer).*
Open the air fryer to see if they are cooked enough for you, and heat them for a couple more minutes if you wish.
Serve while warm.
Notes
* Adjust the timing of the air fryer depending on how you want your steak cooked.
