Heat a generous glug of olive oil in a saucepan over a medium heat. Add the onion and ginger and sauté gently for 5 minutes. Add the garlic, celery and carrot.
Sauté for 10 minutes before adding the paprika and mint. Give this a minute or two in the pan before adding the lentils.
Stir in the tinned tomatoes, stock and lemon zest. Bring to a boil and then simmer for 25 minutes until the lentils are tender and the soup has thickened. Add some boiling water if the soup has thickened too much.
Stir through the lemon juice and season well.
Serve with crumbled feta and fresh parsley on top and enjoy alongside toasted Organic Six Seed Sourdough.
