Heat olive oil in a saute pan over medium-high heat. Add ginger root, salt, basil, and garlic powder to the oil and stir for 1 minute.
Pour in vegetable broth and bring to a boil. Reduce heat and simmer on low for 15 minutes.
Add the halibut fillets, cover, and simmer for an additional 8 to 10 minutes or until the fish is opaque and firm to the touch. Remove from heat and evenly divide halibut and broth between bowls for serving.
