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.

If this was called "Medium Roast", I would give it 4 stars. It's a good coffee. But this is called French Vanilla Caramel, and this review is based on the product's name. Let me say that vanilla and caramel are perhaps my favorite flavors... coffee, ice cream, candy, you name it... if it's vanilla or caramel, I love it. With the exception of this. Where's the vanilla? Where's the caramel? And don't get me wrong: I'm not trying to say that the flavors are too mild. I'm saying that they are NON-EXISTENT. And therefore, based on the name, this coffee gets 1 star.

I have never used Tahini before - and my hummus was good, but always, something was missing... After I found out of Tahini, I ordered it (and it was shipped extremelly fast)and used it. The result was amazing! One spoon into the hummus prepared from one bag (1lb beans) and I had my favorite ready to go!
