After a shopping trip, freeze everything that is freezable, and make a note in a record book of what you have in the freezer and when it has to be used by - also whether you need to defrost it before cooking or can cook it from frozen.

For fresh foods, especially salads and vegetables, don't over-buy unless you have a planned meal or occasion coming up. It is tempting to buy things when you see them or when they are on offer, but it is a false economy if they get wasted.

This is somewhat obvious, but when you do your vegetable shop, try to use it up in the order at which it goes past its best - e.g. broccoli first, then sprouts, leaving things like carrots and leeks to the last as they tend to stay usable for longer.
