Start by cubing your chicken breasts and add them to a bowl with your pickle juice and coconut sugar.
Next, stir your chicken until its fully coated in the brine, cover the bowl, and place it in the refrigerator for 30 minutes to marinate.
While the chicken is marinating, preheat your oven to 400 F.
Next, line a baking sheet with parchment paper and set it aside.
In a separate bowl, whisk together your eggs and set it aside.
Then, mix your dry ingredients together in another bowl.
Once your chicken has finished marinating, dredge each chicken nugget into the egg wash, then place it in to the dry ingredient mixture to fully coat it in the breadcrumbs.
Line the chicken pieces onto the baking sheet, then bake them for 12 minutes, being sure to flip them halfway through.
Once they're done, broil them on high for one minute, to get some extra browning.
Remove them from the oven, and enjoy! Store any leftovers in an airtight container in the fridge, for up to one week.
