In a large soup pot, water sauté (or sauté in olive oil) the onion, garlic, and ginger together for 3-5 minutes.
Add veggie broth & mushrooms. Bring to a boil. Turn down to low and simmer for 45 minutes.
While broth is simmering, boil water for ramen noodles. Cook according to package (usually 3 minutes) and set aside.
Once broth is ready, using a strainer spoon (or if your pot has a strainer lid), separate the onions, garlic, ginger, & dried mushrooms from the broth.
Next add your veggies of choice to the stock and simmer for another 10-15 minutes until veggies are tender (to your desired softness)
Ladle soup into each serving bowl and then put I ramen noodles. Top with anything you desire (fresh basil, hoisin sauce, siracha, lime juice, etc)
