Add milk, pickle juice, then chicken pieces to a large bowl. Stir to mix well, making sure chicken is covered in brine. Cover and refrigerate at least 1 hour and as long as 3 hours.
When chicken is finished marinating, pulse crackers, breadcrumbs, flour, paprika, salt, pepper, and powdered sugar in a food processor.
Coat nuggets in breading mixture (either by dredging or by adding to a gallon bag and tossing) and working in batches, fry in peanut oil over medium high heat (about 350°F) until cooked through and golden brown on all sides.
While nuggets are frying, prepare rolls according to recipe or package instructions.
In a small bowl, whisk together butter and honey, then brush it over biscuits. Split the rolls open and tuck a nugget into each one.
