There's an interesting one too.
We call it dragonfruit. There are 2 types i know of. One is white on the inside and the one you had was red. The texture is similar to kiwi but i don't find the taste the same. Maybe because i like the little bit of sour in kiwi. I've read the skin can be eaten too but 8 think people still peel away the outer layer and use the inner for some kind of salad or vegetable
