Preheat your oven to 400°F (200°C).
Line a baking sheet with parchment paper.
Cut the chicken into bite-sized pieces.
In a mixing bowl, combine the cold water, 1/4 cup Parmesan cheese, salt, and pepper. Whisk until well combined.
Dip each piece of chicken in the wet mixture, letting excess liquid drip off.
In a separate bowl, mix panko breadcrumbs with the remaining 1/4 cup Parmesan cheese, then coat the chicken pieces.
Place the coated chicken pieces on the prepared baking sheet in a single layer.
Bake for 15-20 minutes or until cooked through and golden brown.
Let cool for a few minutes, then serve with your favorite dipping sauces.
