In reply to BoaseF:
We use a lot of those flavoured cous-cous packets that you get in supermarkets, with additional stuff added (cheese, chorizo, nuts etc) to give it a bit of interest.
But it depends a lot on whether you're talking about the "carrying all your food" type of camping meals, or "hunched over a pocket rocket in a rainy campsite", or "sat at the dining table in your house-sized family tent". Pasta with stir-in sauce and maybe extra veggies is great if you're car camping, for instance, but I'm not going to cart half a dozen jars of Dolmio halfway across Scotland in a backpack...
