Hi and welcome!
All meat and veggies need to be weighed and measured before cooking.
You should be using sea salt.
I also read about some not using bars for the first couple of weeks but my coach gave them to me and said I could have one per day, I haven't had any problem losing having them!
Sorry, I have no idea about the balsamic...I don't like it so didn't pay any attention!
Just make sure to follow your sheet and you will do just fine!
