I love food, and I love cooking. I am a believer that any fool can rough it, but to camp in comfort simply takes a little thought.

Basic one pot recipes then.

Chicken curry (or chili) and rice.
Take a tin of chicken curry, peel the label off and wash the tin. If you are smart you do this at home, and then simply mark the lid with the contents in permanent marker. Pierce the lid in two places.
Bring some water to boil in your mess tin, normally half a pint or so.
Stick your tin of curry in, piercings upwards.
After 5 minutes, add a pouch of quick cook rice to the water.
When the rice is cooked, the water should be used up and in the rice. Open the tin of curry, pour over and devour.

The same method can be used for tinned stew and tinned spuds. But just empty the spuds straight out into the mess tin and cook in the tin water, with the stew in it's tin. Careful draining is required.

Sausage Bolognaise.

Feeds 2.

Pack of Aldi Bratwurst
Pack of Aldi fresh tagliatelle (or other fresh pasta)
Carton of passata
Few mixed herbs.
Tabasco.
Salt and pepper.
Oil or butter.

Stick the oil or butter in your mess tin. Begin cooking the sausages. After 10 minutes add a splash of water and then the carton of passata, herbs, tabasco and salt and pepper. Bring to a simmer and add the pasta. Simmer for 2-3 minutes more and eat.

One of my favourites is the Batchelors Pasta and sauce. Dried food, so it's light, and easy to do.
When I used to do a lot of walking I went to the trouble of buying the dried mince/soya from healthfood shops, mixing it in bags with herbs, chili flakes and pasta, and then simply boiling the lot with a squeeze of tomato puree from a tube to add a bit more flavour. Super lightweight and very little mess to carry.
