Boil water in a large Dutch oven. Once water boils, throw broccoli, carrots, and mushrooms into the water for 2 minutes. Using a slotted spoon, remove the vegetables to a colander.
Using the same boiling water, next place the shrimp in the Dutch oven and let boil for about 3 minutes until the shrimp turn pink.
Add the shrimp to the same colander to drain as the vegetables, this time discarding the water.
Peel outer layer of daikon, and then using Spiralizer, spiralize into "noodles" using blade A.* Can peel into shreds with a peeler if you do not have a spiralizer.
Bring 6 cups of water to boil again the the Dutch oven. Once boiling, add the miso paste, cover, and bring to a simmer for 10 minutes, mixing occasionally until the miso completely dissolves.
Once the miso soup has dissolved, add all the vegetables, shrimp, and daikon, and heat for 5 minutes on a simmer. Serve immediately.
