Place lentils into a saucepan, cover with water and bring to the boil. Simmer for approximately 20 minutes or until lentils are soft. Drain the lentils thoroughly, rinse under cold tap, shaking off any excess water. Transfer to large bowl. Whilst lentils are cooking prepare the remaining ingredients.
Gently mix all above ingredients together in a large bowl. Check seasoning, then transfer to a nice serving platter.
Serve as a salad in its own right or as part of a middle-eastern mezze plate, with hummus, falafels, pitta bread, Turkish flat bread, labneh, grilled meats, fish, haloumi and so on.
