A very versatile dish - you can add various herbs and/or spices to make this Indonesian, Thai, etc. Though it's also nice without any extra herbs & spices added; When I first came up with it, it had none & we served the cashew sauce over onions, carrots, sliced portabella mushrooms and asparagus.

You'll want to make enough of the sauce that the final dish is slightly runny, not just enough to marinade the veg.
