Instructions
Heat 1 tablespoon of rapeseed oil in a large pan over medium heat. Add the 2 finely chopped leeks and 1 large courgette. Fry them for 5 minutes until they start to soften. Pour in 1 liter of vegetable stock. Add three-quarters of the cannellini beans (approximately 300g) and all 200g of green beans. Add half of the chopped tomatoes (approximately 1.5 tomatoes). Bring the soup to a simmer. Cook for 5 to 8 minutes, or until the vegetables are tender. Meanwhile, prepare the pistou sauce. Combine the remaining cannellini beans (approximately 100g), the remaining half of the chopped tomatoes (approximately 1.5 tomatoes), the 3 chopped garlic cloves, and the small pack of basil in a food processor. Blend until the mixture is smooth. If you do not have a food processor, use a stick blender in a bowl. Stir in the 40g of Parmesan cheese into the blended mixture. Add the prepared pistou sauce to the simmering soup. Cook for 1 minute more. Ladle half of the soup into bowls to serve immediately. Or, pour it into a flask for a packed lunch. Chill the remaining soup. It will stay fresh for up to two days in the refrigerator.
