01 - Combine cold water, kosher salt, and sugar in a large mixing bowl, stirring until fully dissolved.
02 - Submerge the chicken or turkey breast in the brine, cover the bowl, and refrigerate for 4 to 8 hours to ensure thorough seasoning and moisture retention.
03 - Set the oven to 325°F and allow it to reach full temperature before proceeding.
04 - Remove the meat from the brine and pat it thoroughly dry with paper towels. Evenly coat the surface with black pepper, garlic powder, onion powder, smoked paprika, and dried thyme, gently rubbing the seasonings into the meat.
05 - Roll the seasoned meat tightly in parchment paper, then wrap securely in aluminum foil, twisting both ends to form a firm, compact log shape.
06 - Place the wrapped meat log on a wire rack set over a rimmed baking sheet to allow even heat circulation.
07 - Roast in the preheated oven for approximately 1 hour, or until a meat thermometer inserted into the thickest part registers 162°F.
08 - Remove from the oven and let the meat cool completely, preferably refrigerating overnight, before slicing thinly for sandwich use.
