Meanwhile, place the passata and stock in a frying pan over medium-high heat. Bring to a simmer. Cover. Reduce heat to medium. Cook for 3 minutes or until heated through.

While the sauce is cooking, process the bread, garlic, parmesan and lemon rind in a food processor until coarse crumbs form. Add the tuna, parsley and eggs, and process until combined. Season with salt and pepper. Roll tablespoonfuls of tuna mixture into balls.

Add tuna balls to sauce. Cover and cook for 8 minutes or until tuna balls are cooked through. Divide pasta among serving dishes. Top with the tuna balls and extra parsley.
