Firstly, finely dice the onion, crush the garlic, slice the mushrooms and chop the carrot.
Place a large pot on a medium heat adding the olive oil, garlic, onion, carrot, mushrooms and herbs and fry together for a couple of minutes until they soften.
Then add the tinned tomatoes, drained lentils, vegetable stock cube or pot and tomato puree and mix together. Place a lid on top and cook on a medium to high heat for 15 minutes until the bolognese starts to thicken, making sure to stir it every 5 minutes.
Meanwhile, boil the spaghetti as per packet instructions.
Finally, serve a few generous spoons of the bolognese sauce on top or mix into the pasta and enjoy.
