I have a small paperback book called 'Will it Freeze?'
It is a valuable source of info when avoiding food waste

You might not know that bananas should be kept away from other fruit because as they ripen they emit a gas which causes other fruit to ripen faster, and, rather than throw away overripe bananas, you can freeze them pureed for future use in smoothies and cakes.

Overipe tomatoes can also be pureed and frozen for use in sauces and soups

PS - dont throw away limp lettuce -make soup
