We don't buy any meat or meat products (sausages, bacon, ham, pate etc) - all home produced, lamb, mutton, pork, duck, chicken, and so on.
We produce all our own milk, butter, cream, ice cream, and soft cheese. We do buy hard cheese.
Virtually all our veg is home grown, but do buy quite a lot of fruit out of season.
Home produced eggs too.
It is relatively easy to have a home produced dinner once in a while - the challenge is to do it every day of the year.
