There are many ways to save a little money here and there and it all adds up! I bought a lot of extra bananas a while back because they were on sale (of course!). I usually use brown bananas in smoothies but I had too many this time, so I decided to make banana bread!
You can use leftover bananas for banana bread, smoothies, banana muffins or even banana cookies! Bananas also freeze so if you can't get to them right away you can keep them in your freezer until you are ready to use them (although they are a bit mushy and watery when thawed-they still work well for baking.)
Here is a banana bread recipe to try: http://www.simplyrecipes.com/recipes/banana_bread/
We usually eat one loaf right away and then I freeze the other one for later on. Yum!
