Chop vegetables into 1 inch pieces.
In a large stockpot, heat oil over medium-high heat. Add vegetables and sear to caramelize the outside. Be careful not to burn the garlic.
Add both broths and water to the pot and bring to a boil.
Reduce heat and simmer 1 hour.
Use a slotted spoon to remove veggies.
Serve with thinly sliced mushroom and chopped green onion.
