Hmm ... this is a tough one.

I second Hood's CC chocolate milk. SO good. And I also really like all the LC ice cream, especially chocolate. (I've never tried Atkins.) RS chocolates, too.

Okay, leaving the chocolate for now, Mama Lupé's LC tortillas are quite good. And this isn't particularly marketed as LC, but Fifty-50 makes yummy sugar-free jellies. Oh, and LC V8 Splash is good as well.
