Wasabi (peas) brussel sprouts?
I once attempted to make Brussel Sprout Chips (in much the same way you can make Kale chips)... That worked... now if you can make a wasabi sauce/dressing or sprinkle freshly grated Wasabi so it bakes onto the sprout leaves you may have something...


Preheat the oven to moderate oven 180°C/350°F. 
Remove the leaves of the brussels sprouts. This is tedious work, but it can be done. You want as many leaves as possible, and you may need to keep cutting away the stem as you get deeper into the sprout.
Place the leaves on a baking sheet and drizzle generously with olive oil, tossing to coat. Sprinkle with the sea salt/wasabi/whatever dry flavours.
Bake, turning every 5 to 7 minutes, until browned and crunchy, almost burnt, but not burnt.
