Unlike M&M’s, they are pareve. At least most of the time, if not all the time. I don’t know if they make them milchiks, but if they do, I probably wouldn’t call them “chocolate lentils”; I would probably call them “Cholov Yisrael M&M’s” or “Cholov Yisrael Reese’s Pieces”.
Speaking of which, can anyone explain to me why no one has yet invented Cholov Yisrael Peanut Butter Cups? Someone I know made them once, and they tasted as good as the real stuff, so there’s no excuse.
If someone were to do that, there would probably be a tremendous market for it, and I would probably start keeping Cholov Yisrael since there would no longer be a reason not to.
