A couple of weeks ago, I had an entire bunch of bananas about to go bad. I had forgotten about them. Just before they went bad, I remembered about them , peeled them, chopped them into pieces and tossed them in the freezer. Then I forgot about them again. Tonight I remembered about them and boy, am I glad I did!
I took about half of my frozen banana pieces (2.5 or 3 bananas worth) and put them in the food processor (i've tried with both regular and rocket blenders, it doesn't work, believe me) with 2 spoonfuls of cocoa powder and a large dollop of peanut butter. That kinda stuff is all add-ins, so just eyeball it.
Then blend until it's all nice and creamy and eat!
It's cool, creamy...it even melts like ice cream but it's non-dairy, low fat and calories. Heck, if you didn't add the peanut butter, it'd be just as healthy as eating a few bananas (but WAY better). Also, if you factor in how inexpensive bananas are, it's probably as inexpensive as ice cream.
