Heat a little olive oil in a frying pan over medium heat.
Add the chopped onion and cook for about 5 minutes until soft. Stir in the garlic and cook for another minute.
Add the turkey mince and break it up with a spoon. Cook for 5–6 minutes until browned all over.
Stir in the tomato purée, oregano, paprika (if using), and Worcestershire sauce. Cook for 1 minute to release flavour.
Bring a pan of salted water to the boil and cook the spaghetti until al dente.
Add the chopped tomatoes to the mince, reduce heat and simmer for 10–15 minutes, add sliced cherry tomatoes stirring occasionally.
Drain Spaghetti then toss very lightly with a small spoonful of the finished Bolognese sauce.
Plate up a nest of spaghetti, spoon the turkey Bolognese neatly on top, and finish with a generous grating of Parmesan and optional fresh herbs.
