Begin by making your yogurt honey dijon sauce. Add all ingredients to a small bowl and whisk together until well combined. Set aside in the fridge while you are preparing the chicken bites.
Add your cubed chicken to a medium bowl and combine with 1/2 teaspoon kosher salt and whisked egg.
In a large bowl, whisk together the remaining salt, spices, black pepper and tapioca flour.
In a heavy bottomed large cast iron skillet, add your avocado oil, and turn on heat to medium high. While your avocado oil is warming, begin breading your chicken in three batches.
In 3 batches, add the egg coated chicken to the tapicoa, coating very well. Transfer to a sheet pan while you bread the others.
Before adding the chicken, make sure the oil is hot enough by dropping a bit of tapioca mixture in the pan to see if it sizzles. Oil will take 4-5 minutes to heat up all the way.
Add chicken to the hot pan, in batches, in a single layer and leave undisturbed.
Cook chicken about 2-3 minutes on each side until golden brown and just cooked through. With each batch, you may need to adjust the heat and turn it down a bit.
Transfer to a paper towel lined dish to drain excess oil. Finish with a sprinkling of kosher salt then serve hot with dipping sauce on the side.
