I bought a pastured boneless turkey breast at the farmers market today. It weighs approx. 4 pounds. It is still in the packaging, but does not appear to have any skin on it. It was expensive, so I don't want to mess it up. I bought it not with dinner in mind, but to slice for sandwiches/salads for lunch this week. Should I brine it? What temp to cook it on? Any suggestions would be great!
