Mince garlic, mix with softened butter, spread on Italian bread slices, and toast in a 400°F oven for 3 minutes.
Heat olive oil in a large skillet over medium-high heat, season cod with salt and pepper, and sear 3 minutes per side until cooked through.
Pour canned tomatoes and olives into the skillet around the fish, simmer 2 minutes, and season the sauce with salt and pepper.
Divide cod and sauce among four plates, serve with garlic bread, and enjoy.
