mmmm. Sounds tasty! I had some Banana's that had black skins and I was about to chuck them in the bin and i thought I wonder if you can freeze banana. So i sliced them up as they were all ok inside, lined them on greaseproof paper with a gab between so they did not freeze together as one chunk. Left them all and froze them overnight. Next day took them out and mmm tasty snack. However they thaw fast and do not look appetising at all when doing so, so just take what you need. I then broke a few up and mixed with a couple of mullerlight yoghurts in my ice cream maker and i have free yummy ready to eat ice cream.
