Just started using a ‘sous-vide’ machine to cook frozen, boneless chicken breasts, then slice them. Going to try it with that turkey as well. The machine has no bells and whistles (no app or anything) and was $80 on Amazon.
The chicken comes out really moist. You can throw dry-rub in the ziploc bag to add flavors. Had tried different cooking methods but the result this way has been the best.
Price comes to a fraction of store-cooked or deli meat. Helps the budget if you have a teenager doing school sports.
