Having a well stocked freezer is one way of saving money.
Buying in bulk has always been cheaper than buying small amounts of food stuff.
I bought a large family pack of chicken breasts that were on offer. Cut into equal portions that would easily serve two or more people. Remember we all need to eat less food and certainly a lot less meat.
One pack of chicken meat divided in to 7 meal packs for at least two people each. All now in the freezer except one which will be used for tomorrow to show how far I can make it go.
