Preheat the grill to medium setting. Place the sausages on a shallow baking tray and grill for 10-15 minutes
or until golden-brown all over. Turn half-way through cooking. (Alternatively heat a dry frying pan over a medium-low heat and fry the sausages until browned on all sides). Allow the sausages to cool slightly before slicing into bite-sized pieces.
Heat a large saucepan over a medium heat and add the butter. Once melted
add the onion and carrot and fry for 8-10 minutes
or until the onions are soft and translucent and the carrot softened. Add the garlic and thyme sprigs
and fry for two minutes or until they become aromatic.
Pour in the lentils and stir round with the vegetables. Add the stock and roughly mash the lentils with a potato masher
then add the sliced sausages and bring to a simmer. Simmer gently over a medium low heat for 10 minutes or until the soup has thickened slightly. Add hot water if the mixture is becoming too thick.
Remove the thyme sprigs
then season to taste with salt and pepper and serve hot.
