I never checked the soup list before and was surprised at the number of different ones there. Why did I think it was only tomato--probably because that is the only one I eat. Any brand is ok, just avoid the "cream" soups. Stick with vegetable or beef or barley varieties.
I don't have the Food Companion for Core. I have them from other programs I have worked. You would only need them for the points value of foods so what you have is probably ok.
The Eating Out Companion, I have heard, is not too helpful either except that, again, you would have the points for foods you might eat and use your WPAs for.
Welcome to the Board and I hope you enjoy Core as much as we do. I will be looking forward to your posts.
