Abstract: A system for processing pieces of protein includes a freezer unit that receives the protein pieces in an uncooked state and retains the uncooked protein pieces at a temperature and for a time interval to crust freeze the protein pieces to a depth sufficient to impart dimensional stability to the uncooked protein pieces; a packaging machine that receives the protein pieces from the freezer unit and retains the protein pieces in cooking pouches; a batter applicator that deposits a batter made from high-gluten flour in the cooking pouches to coat the outer surfaces of the protein pieces; the packaging machine programmed to vacuum seal the batter-coated protein pieces in the cooking pouches; and a heating unit programmed to sous vide cook the protein pieces in the cooking pouches for a time and temperature selected to completely cook the protein pieces and leave the batter sufficiently tacky to adhere to breading.
