I like a good veggie curry, with potatoes, sweet potatoes, chick peas and carrots and onions, mixed into a jar of patak's sauce (only time I don;t make my own currys is when camping.
Served with ready made naan bread. Lush.
Chicken and veg stir fries with noodles also good and easy. Any old recipe will do, and a wok.
DS's favourite is couscous mixed with tuna, cherry tomastoes, chick peas, cucumber and peppers. The best thing about it is that all that needs to be done on the stove is boil the water for the couscous.
I don't eat pasta at home so don't bother with it when camping either.
BBqs are of course lovely too. I just pick up some mince from a local butcher and quickly make it into patties, bbq them and have them in buns with lots of salad.
I also like making a stew at home, freezing it, and it tends to defrost by the end of the first full day of caming, and it's a nice easy way of having a good hearty meal after a day of climbing when my fingers are too sore to manage actually preparing and cooking anything.
