Preparation

• Finely chop the onions and garlic and fry them well in a deep frying pan. Add the spinach and let it wilt over medium heat. Then add the chopped tomatoes. And let these also lose quite a bit of their moisture over medium heat. If you have the tomato sprig, add it to the sauce. It gives off a wonderfully deep tomato flavour. Then add the lentils. Stir well.
• Then add the mustard to taste, as well as the salt and pepper. You can add a splash of crème frache if you want to make it even creamier.
