Now correct me if I'm wrong but that seems, to a home cook, a reasonable amount of money with which to work. Okay, you may not get haute-cuisine but with that level of expenditure there's plenty of scope for a varied and interesting diet.
My personal secret is cheap meat. Not nasty burgers made out of cow's ears and the like but good stuff, reared to acceptable standards that's nearly always to be had at the bargain basement end of the supermarket chill cabinets.
more exotic spicy sheekh kebabs as part of a yummy feast with the other pack that I'd picked up at the same time. You must know how to concoct this easy-peasy staple of British cuisine. Just brown the mince. Fry up onion, garlic and carrot in the meat fat and then mix all together with a can of crunched up plum tomatoes, herbs and seasoning. Top with mashed potato and grated mature cheddar in an ovenproof dish and freezer container for later on. Pop in the oven at Gas Mark 6 200 degrees Celsius until crispy and lush.
The freshly cooked dish did for supper and there was enough over for Louis' tea the next day. Each of the tupperware tubs contain enough for hearty meals for two on a day when I can't be bothered to cook from scratch. There may be a bit over then depending on how hungry we are on the day. Now I didn't price this up but it easily comes in at under £1 a portion. With frugal porridge for breakfast that leaves plenty of scope for a good balanced packed lunch. Living on £3 a day doesn't seem half bad at all!
