Another Exotic Fruit - Pitaya (Dragon Fruit)

I learnt about this fruit when I went on a trip to St. Thomas, US Virgin Island. At the hotel I was staying they had an exotic fruit tasting and that was the only fruit that was not growing on the island. Because it was the only fruit I've never tasted it got my attention and OMG I was in for a surprise!
It tastes something like in-between kiwi and pear and its flesh is very soft and juicy. The seed are really small and barely noticeable.
A very interesting fact about this fruit is that its tree belong to the cactus family.
Here what it looks like:

And that's how it looks when cut and that's exactly how I eat it!
