Peel sweet potato and cut into 1 inch cubes. Add to a small pot of water and bring to a bowl. Let boil for about 10 minutes until sweet potato is fork tender. Mash and set aside 1/2 cup.
Pre-heat oven to 400° and line a baking sheet with parchment paper.
Spread panko bread crumbs over parchment paper and give a quick spay with a misto, or other olive oil spray.
Bake in the oven for 3 minutes then turn the tray and bake another 2-3 minutes or until bread crumbs are browned.
Meanwhile, add ground chicken to medium sized bowl and add 1/2 cup Parmesan cheese, sweet potato, 1/2 teaspoon salt, pepper, and garlic and onion powder. Mix well.
When bread crumbs are toasted, add to a medium sized bowl with Parmesan cheese and 1/2 teaspoon of kosher salt and mix.
Gather with your hands a small amount of ground chicken mixture and shape it into an oval shape and then gently dip them into the bowl of panko bread crumbs and coat fully with panko bread crumbs. Line them on parchment paper lined baking sheets.
Bake for 25 minutes or until internal temp of nuggets reach at least 165 degrees.
Serve with your favorite dipping sauce!
