Beans seem expensive, but six dollars a bag is only a dollar a cup dry, fifty cents a cup cooked, so you always end up with 3 kilos of fifty cent meals. That is really the only way you can afford to buy oil, vegetables, meat, fish, eggs.
So week one of beans is pretty miserable but by week two it's chicken and lentil soup, beef and bean chilli, hueros rancheros, fish curry and the beans become tolerable.And by week three you can buy sauces and spices and you're back on budget. Freeze bean feeds in 500g zip locks.
DSP neets can just buy nodoze, pizza and fat lambs, but the JSP neets have to suffer vile gas.
