Well those 1000 posts have a point while I can walk into my local co-op and buy a bag full of processed crap for 4 people for a fiver, but the makings of a healthy cooked from scratch meal is £10+ People counting every penny will go for the cheapest option.
But again this is essentially ignorance, isn't it? Of how to cook, what to eat, etc.?
A staple in my country is lentils cooked with chopped up onions and sweet potato, and sometimes chopped tomatoes. Eat with rice.
Rice and lentils are both dirt cheap. Two sweet potatoes and two onions costs about a pound in total?
500g of lentils = £1
2 sweet potatos = 50p
2 onions = 20p
500g of rice = 25p
if you add herbs/seasoning that's about 10p maybe. Tin of chopped tomatoes is 30p.
So that's £1.95 - £2.35 for a big meal for four.
