Using cheaper cuts of meat helps bring down the cost of favourite meals too. We tend to use chicken thighs as they are cheaper than breast but also tastier IMO. Mince, chuck steak (has to be slow cooked) are all cheap. For a portion size of meat it is usually 100-150g of meat. If you are buying supermarket packs of chicken breast they are usually sold in 500g lots so for two people that is way too much meat
