I am an efficient shopper, but I am not sure how much I spend as some food is bought weekly, a big shop every 5 weeks, I buy meat from the local farm shop roughly once every quarter.
However, all my meat comes from the producer and is organic or near organic (but we eat smaller portions because good quality, high welfare meat is expensive).
I plan my menus a week at a time and my food waste bag each week rarely contains more than few bacon rinds, fish skins, and meat bones. Vegetable waste is composted and used to grow the next year's fruit and vegetables.
Weekly expenditure varies from £ 10 to £100, 5 weekly between £125 - £175, meat £30 - £125.
