Heat the oven to 200°C/fan 180°C/gas mark 6. Put the sausages in a large, sturdy non-stick roasting tin and bake in the oven for 10 minutes.
Remove the tin from the oven and turn the sausages. Add the mushrooms and tomatoes, and drizzle with a little olive oil, then dot the tomatoes with the marmalade, thyme and seasoning. Return to the oven for another 10 minutes.
Remove the tin from the oven and cook for a further 5 minutes. Crack in the eggs and return the roasting tin to the oven for 6-8 minutes or until the eggs are cooked how you like them.
Then allow everyone to help themselves.
Boudin noir is the French equivalent of black pudding. It differs from the British version in that it contains finely chopped onions, rather than oats or barley. It has a smoother texture than British black pudding and is less highly spiced, giving it a paté-like quality.
