Heat olive oil in a large skillet over medium heat. Add garlic, breadcrumbs, and season with salt and pepper. Cook, stirring occasionally, until they are toasted and golden brown, about 5 to 6 minutes. Remove and transfer to a small bowl.
Fish:
Add sauce and broth to a large high-sided sauté pan over medium heat and bring to a gentle simmer. Season fish with salt and pepper. Place fish into the sauce and cover with a lid. Poach the fish for about 6 minutes, until cooked all the way through and can be easily flaked with a fork.
To serve:
Place a generous scoop of pasta into a shallow bowl, top with fish, and a big ladle of the sauce. Sprinkle with toasted breadcrumbs and parsley.
