In reply to sausage:
Similar to one previous mentioned but, for light fast cooking hot tasty one-billy alpine climbing main bivvi meal:
1. Instant veg soup in a sachet, add water
2. Add some dried onion, and dried peas (can be premixed with soup at home)
3. Add precooked smoked spicey sausage of some kind chopped up (eg. kabanos)
4. Optional: add chopped fresh capsicum if you can be bothered (tasty extra)
5. Bring that to the boil
6. Remove from heat and add appropriate amount of instant mashed spud and stir, to bulk it up
Yum.
Just as quick as cous cous, but potentially has more energy value, bulk, and taste.
