Quest Protein bars

Hi Transplant Family! 😊
I hope all is well. I am a six year post kidney transplant patient.
My neighbor gave me a taste of her Quest chocolate chip protein bar to try. It's delicious!!
I would love to add these to my list of convenient snack foods that I can keep in my purse, but I am not sure about protein bars for my new fabulous kidney.
Do you eat protein bars or do you happen to know if they are a problem for kidney transplant patients?
Also, if you don't like to eat protein bars, what snack food do you keep in your purse or car?
Thanks everyone and enjoy the 4th of July fireworks!
