Definitely this is in the 'rest of the world' category rather than anything Thai! The green smoothie trend shows no signs of slowing down and I love them.
You don't really need a recipe, just throw things in a blender, but I make mine like this.
couple of ice cubes
1/2 a frozen banana (peel before freezing - I'm not sure anyone else would be as stupid as me but I froze them at first with the peel on. It doesn't work!)
handful of spinach leaves
a big piece of melon, sliced
a kiwi fruit
a good squeeze of lime
almond milk (or soy milk, or coconut rice milk)
2 teaspoons bee pollen (sometimes I have this, sometimes I don't)
