All the recipes were simple enough to make without any ingredients that made you would have to google to find out what it was. 
With the chicken section I did switch up the recipes a bit since I was not going to eat a whole chicken, I substituted chicken breast & off I went. 
As far as the seafood section I have no recommendation as I hate seafood. Sorry you are on your own on this one. 
Either way, if you are looking for some new ideas for the staples in your diet this book would be worth picking up
