Presumably someone has done this before, but behold, the yummiest dessert to be made from bananas, strawberries and a bit of water (or juice/ice-tea/fluid sort of thing in a taste of choice). Does it count as sorbet? I'm not sure.
Essentially, you take one or two (one makes enough for two, really) or however much bananas you want, also take about a handful or more of strawberries (can also chop already frozen strawberries), chop them, freeze them and then turn them into paste (add a dash of fluid here). I've used a hand blender but presumably one of those cup thingies would be even easier. Today I did this but added fresh mint from my aunt's garden that I got while we visited her today and it was even more delicious.
If the strawberries aren't very sweet or you like really sweet desserts, might want to add a bit of sugar or honey, but I haven't felt the need for that at all.
