Ex Input:
These are the worst gluten free cookies I have ever tasted.  They were hard, dry and tasted like tapioca flour.  Avoid these at all cost.

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.

I bought these graham sticks based on their excellent reviews and having purchased Earth's Best organic vanilla cookies, had high hopes for a healthy snack to serve my kids.  Needless to say, I should have purchased one box at the grocery store first before committing to 6 boxes through Amazon (which you are unable to return -even unopened boxes- since this is a food item).  The crackers smelled strange even before tasting them.  My 5 year old turned up her nose and refused to eat them anymore after trying a few.  I wish I could describe the taste, but it would be really hard.  It may sound strange for an organic food, but it was almost like a faint chemical smell.  At best, I can say that they weren't anything like a regular graham cracker flavor (even as an organic option they should have a better taste).  My 2 year old did eat some of them without complaint, so I am hoping she will tolerate them through 6 boxes so I feel like I did not waste my money.  Good price, but definitely test one box first to see if you like them.
