Lately I've been doing carnitas on the first night of canoe trips.  I use smoked pulled pork (vac-packed), tortillas, lime juice, fresh red onion and avacado, and some pico de gallo.  It's a quick, no-cook meal at the end of a long hard day.  Hardly any dishes to wash either.  Heat the bag of pork in boiling water or not, it's good both ways.  If its been a hot day, I eat it cold.  On cold days, I heat the pork.

If you're in the Twin Cities, Baker's Ribs in Eden Prairie has the best smoked pulled pork you'll ever eat in your life and they'll sell it by the pound.  I don't even bother to smoke my own.
