Add the chicken chunks, water, lemon juice, oil, salt, honey (or maple syrup), garlic powder, parsley, paprika, onion powder, and black pepper to a large bowl or zip-top bag.
Mix thoroughly to ensure the chicken is evenly coated with the marinade. Cover and refrigerate for at least 30 minutes, or up to 6 hours for deeper flavor.
Remove the chicken from the marinade and drain off any excess liquid. Discard used marinade.
Heat a grill or grill pan over medium-high heat, lightly greasing the surface with cooking spray or oil.
Arrange the marinated chicken pieces in a single layer on the grill. Cook for 3–4 minutes per side, or until the chicken is cooked through and its internal temperature reaches 165°F.
Allow the grilled nuggets to rest for 2–3 minutes to lock in the juices before serving.
