Personally i love my food, and i don't like to 'make do' when i'm out in the hills. I Usually carry some tins for breakfast (Sausage and beans etc) i know the weight puts many off but, i like to enjoy my walking holidays.
I eat a lot of mixed fruit and nuts while i'm walking (My local Tesco's do a 1kg bag which i usually split to something like 250g a day)
Lunch i usually have a boil in the bag meal (these are getting rare in supermarkets), and use the water for a brew.
Dinner i like to cook. i have a small plastic container (I think from a take away) with a variety of things. tomato puree, herbs, gravy, cooking oil, custard, etc, it varies, but you get the idea. I Always have a pudding. Dutch fruit loaf with custard is highly reccomended.
I Understand that people are concerned with weight, but i like to enjoy my time walking, and i think its worth it. Chicken cooked on an open fire, with mixed veg (boiled. use the water to make a packet vegitable soup, or your gravy) is so much more fun in the midle of nowhere.
Bare in mind that the containers for certain foods need to be quite rigid, to avoid a mess in your bag.
P.S. if i'm boiling veg in water sourced in the hills, i think its best to let it boil to sterilise it before adding the veg to cook. not sure if it matters, but i'v alaways done that.
