In reply to Alan M:
Another Summit to Eat fan here... At the very least, unlike some competitors, they have a decent calories value in a single package. There's quite a difference between a bag of 600+ cals and a bag of 400+ cals for a main meal. Makes for more efficient packaging, at the very least.
Not commenting about the flavour and such, since that's very personal. Adding some pepper and spices can work wonders with any lyo food
But you might also consider making your own - although not as efficient as lyophilisation, simple dried prepared food is not that hard to make. And it can be made to your taste. Well-fed expedition member is a happy expedition member Don't underestimate the morale boost of good feeding!
