This is a first for me, and the combo tastes surprisingly delicious!
I used: kangkung (water spinach), pak choi and Thai basil. All three leaves are intensely green, which means laden with nutrients.
To make the taste palatable, I added an apple and a pineapple. Cheers!
Note: there are some contraindications to eating kangkung raw because of the parasite Fasciolopsiasis buski, a large parasitic intestinal fluke that can be found as larval cysts laid on the water spinach (and other water vegetables). However, I think if you have a strong immune system and undertake a parasite cleanse regularly, you will be protected when eating clean organic kangkung.
If you feel more reassured, replace kankung with ordinary spinach or other greens.
