In a large pot, heat the olive oil on a medium heat. Add the chopped vegetables (onion, carrot, celery) and sauté for a few minutes until slightly softened. Then stir in the crushed garlic.
Add all of the seasoning (paprika, oregano, cumin, salt, pepper) and sauté for another minute to start releasing the flavors.
Now add the lentils, diced tomatoes, broth/stock and bay leaves. Bring to the boil, then simmer for 25 to 40 minutes or until the lentils are tender (Different kinds of lentils take different lengths of time to cook. Green usually take longer than brown.)
Serve in bowls with a teaspoon (or more) of vinegar stirred through. If you like, also drizzle over a little extra virgin olive oil, crumble over a little feta cheese and serve with crusty bread or toast with olive oil and salt.
