Trim & cube chicken into bite-sized pieces.
In a shallow container, add cold water and cold egg. Sift flour into the container. Mix with a fork, but do not beat or whisk. Gently swirl the fork around in the batter until the flour is mixed in and the batter is smooth.
In a second shallow container, combine breadcrumbs, salt, and cayenne pepper. Mix until combined.
Preheat the Ninja Foodi, with the basket in, on broil for 10 minutes.
Coat the chicken pieces in the wet batter and then coat in breadcrumbs. Place the coated chicken onto a cooling rack until all the pieces of chicken are coated.
Spritz the basket with oil of your choice and place the chicken nuggets in a single layer and spritz the top of the chicken nuggets with oil.
Close the TenderCrisp lid and select Air Crisp on 360°F/182°C. Air Crisp for 5 minutes and flip. Spritz with oil and Air Crisp for an additional 3-5 minutes or until the chicken nuggets are golden brown and the internal temp has reached at least 165°F/74°C
Remove and place on cooling rack until ready to serve or toss in your favorite wing sauce!
Serve & Enjoy
