We wanted the Baconnaise lite after seeing the product on Oprah. We looked forward eagerly to the  prospect of that great bacon taste. The decision in our house was 1 for and 1 not so. The taste is there, the "greasy" taste was also. I won't buy the product again.

I love canned sardines and when they put me on a low salt diet I figured that was the end of my sardines until I found these. They taste fantastic,the price is reasonable and you can at least have something that before these sardines was not available to people on a low salt diet. Side benefits as they are skinless and boneless. Thanks to the Roand Co.

I bought this coffee in Jamaica ($15 for 1 lb bag).  While I liked and enjoyed it, I prefer several coffees from my local shops at about the same price.  I think that it may have been worth the $15/lb, but no more.  Certainly not at these prices.
