I'm pretty sure it says somewhere in the book that you can substitute any kinds of mushrooms if the ones specified in the recipe are not available. Buttons are the most common ones here, but most of the others are reasonably accessible too.

I'd be hesitant about cooking a dish that doesn't specify it if you really want to get the most out of the LCD. The heating process can damage some of the nutrients in the vegetables which need to be there in order to get the right stuff happening in your guts. In many cases, it's the combination of ingredients that make that happen, other times it's the fact that the recipe is raw.

I think adding some things on top of what's in the recipe would be ok though. I know I've done that before.

Kale isn't a vege that's readily available here. It's an asian vege isn't it? I think it's available in some of the asian produce shops over here.
