I'm a person who will definitely not eat a banana that is past its prime. I completely understand the option to just throw it out since bananas are inexpensive and widely available.

I have a solution that we have instituted here at home if you would like to cut waste on bananas and other perishable fruits and vegetables. We bought a food dehydrator. I was initially skeptical about the utility of the device but after several years of ownership I find it is one of the most useful tools for anyone who cooks at home.

Bananas, even those that are well past the point where I won't eat them, are ridiculously delicious when sliced and dried. The flavor concentrates so that a single banana chip can be like the old Lays Potato Chip slogan - no one can eat just one.

This also works great for berries like blueberries, raspberries, blackberries, goji berries, kiwi fruit, apples, plums, peaches, nectarines, cherries, etc.

We buy them fresh or grow them here and before they reach the toss stage, we dry them for future use. Some of the things are also great frozen. I have several pounds of berries from this year's crop in the freezer now and quite a few available for adding to granolas that we make here at home.

We have made fruit leathers in the past using strawberries and the flavor is better than the store-bought products.

I grow and dry vegetables too. Some of them are also freezer items.

Good luck with the grocery bill.
