Preheat the oven to 400 degrees F.
In a medium bowl, toss the breadcrumbs with 1 tablespoon of the olive oil, the wine and 1 teaspoon of the minced garlic. Spread the crumbs on a pie plate and toast until lightly browned, 8 minutes.
Meanwhile, in a bowl, combine the remaining 1/2 cup olive oil, 1 teaspoon garlic, the arugula, parsley, marjoram, oregano and vinegar. Season the herb sauce with salt and pepper.
Lightly oil a large baking dish. Arrange the halibut filets in the dish, sprinkle with salt and pepper and roast for 8 minutes. Sprinkle the fish with the toasted breadcrumbs and roast until the fish is cooked through, about 8 minutes longer. Transfer the fish fillets to individual plates, drizzle with the herb sauce and serve.
NotesCook's Note: The sauce can be made ahead and refrigerated for several hours.
