Prized for their vegetable protein, soluble fibre, and high folate content, lentils are an essential good-for-you pantry staple. And there is no need to wait for chilly soup weather to prepare lentils. They are also delicious in summer salads like this one. Feel free to substitute two cans (398 millilitres/15 ounces) of lentils (drained and rinsed) for the dried lentils in this recipe.
