My husband refuses to eat fish, but he LOVES this. It only takes 10-12 minutes to make, and is way better than any other kind of Tuna Helper I've tried. Besides the box itself, you'll need: - 1 can of tuna (6 oz., or I use 8 oz.) - 1 tablespoon of butter - 1 cup of milk It's a breeze to prepare, just DON'T leave it alone before you put the tuna and pasta in. Because of the milk, it likes to boil over. Just keep an eye on it and reduce the heat right after it starts boiling.

Many reports are coming out about how chocolate is actually good for you, so eat more! This is the perfect chocolate to do that with. The varying levels of cocoa are perfect to help adjust your taste buds to eating dark, dark chocolate. It's not an easy transition for a milk/semi-sweet kinda gal, but this chocolate is affordable and so tasty. I also like that I can just have one (as they are individually wrapped), and choose my %.

Miss Vickies are better but unfortunately less widely available. I'm not sure tough is the right word but there is a noticeable difference between the two brands and Miss Vickie's are better IMHO.
