It's a staple at my house. We live on them...sort of. :)
These are really easy to make, if you have the ingredients on hand.
All that's needed is:
2 small bananas
1/2 can of coconut milk
2 cups of mango chunks
2 cups of pineapple juice
(okay, I never measure...I just totally made those measurements up. Use your best judgement, you really can't go wrong.)
Blend together and serve in pretty glasses. You can serve with a dollop of whipped cream if it strikes your fancy.
