Prepare your ramen noodles according to package directions, then strain and set aside.
Bring 3-4 cups of water or veggie broth to a boil. Toss in mixed mushrooms and any additional veggies, and allow to cook for 2-3 minutes, or until tender.
Turn the heat off, then scoop a few tablespoons of the boiled water into a small bowl and begin to break down the miso paste, using a fork or chopsticks to whisk out any clumps until completely smooth. Start with 1 tbsp, and add more as desired (miso is naturally salty, so it depends on your taste preference!).
Add noodles back into the pot, and add the whisked miso. (We are adding the delicate ingredients once heat is off, so as to preserve the nutrients and probiotics).
Optionally, garnish with toppings of choice and add additional salt and pepper as desired.
