For the dressing, whisk all the ingredients together except the water. Slowly add water 1 tbsp at a time, until the consistency is as creamy as you'd like. Taste and adjust salt as necessary. Note: for a creamier dressing, add everything to a blender instead!
Assemble your bowl! Add a base of brown rice, top with the roasted brussel sprouts, sweet potato, chicken, and finish with a drizzle of the dressing. Serve with fresh parmesan and an extra squeeze of lemon. Enjoy!
