I find meat free meals cheaper.
You can get chicken style quorn for £1.70 per pack and that can make 2 meals each for OH and I and more - with the rice.
Fresh Quorn is 3 for a fiver in ASDA have a look. I do not just buy quorn, there are other's for example, Linda McCartney!
It is good when Linda Mccartney pies are on bogoff that means pies are about 30p each!
I could not believe it when I saw two chickens for £7.00 today and they were tiny! I would rather spend £1.70 (Asda) for 300g of quorn and do a veg chilli with frozen peppers or a stew both of which could do 2-3 meals each for OH and myself.
Meat is not cheap. But do not think that meat free means just lentils and seeds try the meat free alternative.
