Cut your chicken breasts into small nugget size pieces.
Combine all of your dry ingredients in a large shallow bowl.
In another small bowl, add your egg and whisk until smooth.
Take pieces of your chicken and dip them in the egg wash then the dry mix before setting aside on a plate.
Repeat this process with all of the chicken.
Pre-heat your air-fryer or oven to 375*F.
Place some of the chicken nuggets in the air fryer and cook for ~5min. Flip and cook 2 more minutes on the other side, repeat for all nuggets. (If using an oven, bake on a greased cookie sheet for 20-25min.
To make the sauce, combine all of the above sauce ingredients in a small sauce pan and bring to a boil, whisking well during this time. Boil and whisk for ~1-2min or until sauce begins to thicken then remove from heat.
Serve the nuggets warm with buffalo sauce or with ranch/plum sauce! Enjoy!
Store covered in the fridge or freeze in ziplocks for later re-heating!
