Combine the broth, garlic powder, coconut aminos or soy sauce, fish sauce, lime juice, mushrooms, and stevia (if using) in a medium to large soup pot and bring to a boil.
Once the mushrooms are soft and cooked, add the chicken and boil until it's warmed through.
Just before removing the pot from the heat, stir in the peanuts and allow to boil for 30-60 seconds.
Ladle some cooked noodles into the bowl, then the soup and top with green onion.
