Thoroughly wash and cut brussel sprouts in half. Remove any brown or yellow outer leaves. Add to large bowl. Toss with olive oil, salt and pepper. Transfer to a parchment paper lined baking sheet and bake 15-20 minutes (toss half way through), until they are brown and outer leaves are crispy.
When they’re almost done, remove from oven and add the slivered almonds and half the dressing. Toss to coat, then return to the oven for another 5 minutes. You don’t want the almonds to burn.
Remove from oven, drizzle remaining miso dressing on, mix to coat evenly.
Transfer to serving dish, garnish with shredded parmesan if you want, and enjoy!
