Reheat directions for the neighbors?

I gave a buddy of mine at work a half rack of babyback ribs wrapped in foil. I told him explicitly not to use the microwave. His response was, "so whats the best way to warm them up?" I thought about this for a moment and realized that I had no idea.

I ended up telling him to leave it foiled and throw it in a 325 degree oven for 30min. How close was I?

Does anybody have any simple time/temp/preparation recommendations for reheating brisket, ribs, chicken, pulled pork? If it involves dutch ovens, vac sealers, or sous vide then it is probably too complicated for me to pass on.
