Cold weather cooking - it's all in the preparation

My son, a Tenderfoot Scout, has spent the evening cracking dozens of eggs and cutting up pre-cooked sausage. Why? Because his Boy Scout patrol is in charge of making breakfast for the entire troop at this weekend's Klondike Derby, and they chose to make breakfast burritos. So, rather than crack dozens of eggs and cut up sausage outside in the cold where his egg-splattered hands would get way too much exposure to cold air, he can do these things ahead of time in a warm environment where he also has access to warm water and soap. The eggs have been cracked, whisked, and poured into a gallon jug, and the sausage pieces have been cut up and placed into tupperware. When it's time to actually make breakfast, all his patrol will need to do is heat up the food.
