Query: I buy these by the case -- and they go fast!

Reviewing food is a tricky thing since tastes are extremely subjective. Suffice it to say, I absolutely love these Puppodums. I pop 'em in the microwave and they crisp up perfectly. Although called "spicy" they are not hot spicy, just flavorful.They taste great and are low in calories (20 cal each), zero fat, and suprisingly high in protein (6g for 4) and fiber (4g for 4). I used to be able to find them in Wild Oats but they don't stock them anymore. I was ecstatic when I discovered them on Amazon -- I buy them in a case of 12 boxes and they expiration date is always at least a year away (not that they last that long in my house). Great for snacks as well as with meals.
