Someone one on here recommeded Organic Swiss Vegetable Bouillon to me, and it is gorgeous. Apparently it needs to be the reduced salt version. Anyway I have this and it doesn't seem to effect the diet.
This one has an orange lid though so might not be the one you are after.
Ive tried both (the ones swiss one and the CD one) and i prefer the CD one as its lets salty tasting. The swiss one ive had is the low salt, but its still very salty.
I enjoy my mug of it about 2pm when im hitting a lull and it works a treat.
To me both taste like chicken noodle soup (and smell like it) but without the pasta.
