DH loves turkey, so sometimes I cook just 1/2 turkey breast from trader joes throughout the year. For 7 people, I'd probably cook 2 just to be on the safe side, but then I love having leftovers and always, always cook too much food.
I made one Monday evening, brined it and it was plenty moist - definitely brine and use a meat thermometer.
FWIW I like to use this recipe

This one looked really tempting, but as I read it, it was just too much effort for Monday evening
