One of the things I like to do is to take meals to camp that are already prepared. This is nice if the days are long with very early getups and late trackings for recovery on occasion. I'll take a couple meals like spagetti where all you have to do is heat the sauce, make the noodles, and throw a salad together. After a 15-16 hour day all I want to do is get a meal, take a bath if I can, and hit the rack. 4-5 AM comes too quick the next morning and an hour or more to prep and cook a meal is too long sometimes. This method cuts the time in half or less most of the time.
There are a number of meals that are very good predone that make camp life a bit easier for the cook in the late evening.
