Thawed frozen mangoes
About a year ago, I bought a massive package of Dole frozen mango chunks. The ones I tried immediately upon purchase were tasteless - not sweet, and certainly nothing like mangoes. If anything, they tasted of plastic bag. I forgot about them and realized just this weekend that I had better use these mangoes before they go rotten or grow mould. I thawed out the entire bag in the fridge, and the mangoes taste exactly as terrible as they used to. What do I do with a good two kilograms of thawed, previously frozen mangoes? I dislike tossing food.
I'm diabetic, so disguising the lack of taste with a tonne of sugar (or sugary things, like other fruits) is not the best option. Ideally, I need ideas that would use a lot of mango but have other components that contribute flavour (and hide the mangoes' terrible flavour). I'm vegetarian (yes dairy, no eggs).
Thanks for the help! :) Related question - can dogs eat mangoes?
