Ex Input:
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.

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.

The pancakes were delicious, but they weren't as fluffy as the ones I normally make.  Next time I use this, I'm going to whip the egg whites and see if that helps.
