- 2 tbsp olive oil
 - 2 fat garlic cloves, finely chopped (optional)
 - 7.5cm/3 inch piece fresh root ginger, peeled and finely grated
 - ½ tsp red chilli flakes (optional)
 - 300g/10½oz red lentils
 - 1.2 litres/2 pints hot vegetable stock
 - 300g/10½oz butternut squash flesh, cut into 1cm/½-inch cubes
 - salt and freshly ground black pepper
 
- Heat half the oil over a medium heat in a large, heavy-based saucepan. Add half the garlic, if using, half the ginger and all the chilli flakes, if using. Fry, stirring all the time, for 1 minute. Add the lentils and fry, stirring, for a further minute.
 - Pour in the stock and bring to the boil. Simmer, with the lid off, for 10–12 minutes, or until the lentils are soft.
 - Meanwhile, heat the remaining oil in a heavy-based frying pan. Add the remaining garlic and ginger and the butternut squash and cook, stirring, for 12 minutes.
 - Add the butternut squash to the lentils and cook for a further 5 minutes. Remove from the heat and blitz using a stick blender until smooth. Season to taste with salt and pepper.
