These chips are the only ones I found to be tasty and healthy. They have fewer fat calories plus higher fiber for those who want good taste and nutrition--the perfect blend!

The package came with the label torn off and no cooking instructions. I know how I normally cook Couscous so tried 3/4 cup water to 1 cup couscous-brought to a boil and let sit, covered for 5min. It was mushy and tasteless.We have thrown out the rest of the container.
