I prepare these baked potatoes in a toaster oven. They are the perfect compliment to a hamburger, steak or chicken entree. Try them. You'll like them!

I discovered these when I moved to Canada a few years back.  Before this I had only experienced a thicker Wasa crispbread and was a bit put off at first.  The feelings dissolved the first time I ate one of these with light laughing cow cheese.  They are a little more "powdery" than I'd like, but they compliment most cheeses very well without overwhelming them.

Was very happy that the kids liked these! We all liked them! I bought this mostly for myself. I made them with coconut oil instead of the vegetable oil that it calls for.....it was a yummy, healthy substitute. Will definitely be buying again.
