I have tried 3 different varieties of Kashi frozen meals.  I would rate them as average.  On the plus side, they're healthy - less sodium and fat than you'd expect from frozen meals.  I enjoy the ease of making a frozen meal for my lunch, but dislike the unhealthy qualities of many of my choices.  Kashi scores here.

Also, I found that the meals contained lots of veggies and generally tasted good.

On the downside, I thought the meals were expensive (regular price around $4, higher than comparable meals).  They were not all that filling either - about 300 calories each and not a very large portion. ...
