Tried Mountain House lasagna a couple of nights ago as an experiment to prepare for my upcoming JMT thru-hike. Loved it. Did wish they packed a bit flatter, and they are supposedly a "serves 2" size (which won't matter, since I'll easily eat the whole thing at the end of a day of hiking anyway). But it was delicious, and the whole things fixes and eats in the pack, which in theory, could be washed out and reused as a mixing package for anything else that needs mixing/shaking (i.e., water with Better Than Milk, etc.).
