This is a recipe I learned from mom in France when I was a child. In my family and generally in France, this salad is served with lukewarm lentils. So good!! I always add 3 TBSP of sauerkraut on the side. It goes so well with the flavor of the Dijon mustard dressing. Legumes are so good for you and the #1 food to help fight heart disease! So be sure to eat your beans and lentils regularly.
