When grilling fish and seafood, it is important not to overwhelm the flavor of the meat itself, as it is light and delicate and boasts its own flavor that should be complemented, not overpowered. This Grilled Cuttlefish is served with a homemade garlic parsley pesto that can be stored for up to two weeks as a sauce or dressing for other dishes. Serve the pesto drizzled cuttlefish with a wedge of lemon to squeeze over.
