Cut the chicken breasts in half long ways making 4 total chicken breasts.
In a medium sized mixing bowl, whisk the egg.
Add the chicken to the bowl with the egg and stir to coat the chicken in the egg.
Heat the avocado oil to medium heat in a large pan.
On a large plate, combine the almond flour, tapioca flour, garlic powder, onion powder, parsley, salt, and pepper.
Using a fork or tongs, pick up one chicken breast at a time and place it on the plate with the almond flour mixture and flip the chicken to coat both sides.
Place the coated chicken in the pan and cook for 5-6 minutes a side making sure to only flip the chicken once.
While the chicken is cooking, add the sauce ingredients to a medium sized saucepan and heat on low.
Once the chicken is cooked, use a fork or tongs and pick up the chicken one at a time and place it into the saucepan to coat it with the sauce. Be gentle so the coating doesn't fall off.
Optional- Cover a cookie sheet in foil and place a cooling rack on top. Add the cooked and sauced chicken on top of the cooling rack and broil in the oven on high for 5 minutes. Be sure to watch it to make sure it doesn't burn. This helps give the chicken and sauce a little more crisp and golden color.
