Purple Banana's have medicinal purposes but when they are green you can pick them (they are actually purple, figuratively) and peel them, place them in lemon water and slice them paper thin. Fry them in a healthy veg oil and eat them like banana chips! so good with a dash of salt. Today we did that with lunch, harvested the banana, peeled cut and fried. We have more left for tonight and maybe I will post some pictures.
This banana can also be dried and made into a flour that may be used as an additive more more nutrition in yogurt or baking.
Sweet bananas are a bit different because they don't dry int he same way.
