Chop up the onions and put in a large high-sided frying pan with the oil to saute. At this point you could also add chopped up garlic for taste. Or spring-onions if there's some in the cupboard that you would like to use up.
Boil the kettle, and put use the water to cook the lentils in a pan. Bring to the boil, and keep there whilst skimming any scum off the surface off the water. After a minute or so, lower the heat to a simmer to finish cooking the lentils. They're ready when they're slightly soft. This'll probably take about 15mins in total.
While the lentils are cooking chop up any additional veg that you want to add to the mix.
Once the onions are soft, and the lentils are cooked, add the lentils, chopped tomatoes and any additional veg to the frying pan. Give it a stir, and cook on a medium low heat for around 15mins.
While the bolognese mixture is gently bubbling cook the pasta. Serve by dividing out the pasta, and then generously ladle the bolognese sauce on top.
2 or 3 portions of your 5 a day, (1 from lentils, 1 from chopped tomatoes, and 1 from onion and the optional additional veg)
