Other money saving tips: when I do my cottage pie for the homeless I buy the cheap as chips 20% fat beef Mince and fry off the fat. It's so much tastier I buy it for the family now for literally less than 1/2 the price (and twice the taste).
The other thing to try might be offal: lambs liver and bacon (so quick to make). Soften and colour an onion, quickly fry three rashers (or bacon bits), add scant 1/2lb, cut into strips, liver and cook through in the frying pan, sprinkle of flour (flat tbs) and absorb the fat, add 1/2 pint oxo, and stir to thicken. Serve with frozen mash and a frozen green veg. Pan to plate in 20 minutes.
Kidneys are nice too, devilled on crushed new potatoes and again with green veg.
Both above should come in at about 80p per head. Providing you like offal. My gran used to make me braised, stuffed lambs hearts, as a treat!
Not as good as lokshen but: £3.50 chicken, cover with cold water, add a quartered onion and 3 or 4 chopped Carrots- a chicken cube helps it along without a kosher chicken bring to boil and simmernfor 2 hours, add vermicelli (any small pasta will do). For one day serve the meat as a roast(ish) with roast potatoes and veg using the lokshen as gravy. For the next day (and this works well left overnight in a cold kitchen) lift off fat, remove skin and bones but keep the chicken in. Reheat as a hearty, healthy soup with crusty bread or perhaps followed by a baked potato.
Oxtail plus an onion, carrots, juice of an orange, brown everything on hob, add beef stock, transfer to oven on medium. For 1.5 hours then add pearl barley and/or butter beans and cook in a low oven for about 1.5 hours. Dumplings can be added for the last 1/2 hour. Seems like a lot of oven but will also warm the kitchen area whilst you do other jobs, dc do homework.
Except for the lokshen a desert spoon of red wine vinegar works wonders for the flavour if you can stretch to it.
Taste of christmas: 2 turkey steaks slice and fold stripe, pig in blanket, stuffing ball, and repeat until a skewer is full, brush with warmed cranberry jelly. Serve with roasties, cabbage and Carrots and as you have saved £20 on a fancy turkey or chicken, I'd splash out on a pot of poultry gravy, use the cranberry jelly and a packet bread sauce. Tastes exactly the same as a Christmas dinner.
