What are some great ways to start up becoming vegetarian for at 8 year old?

First, I suggest talking to your parents or whoever cooks for you to see if they will make more vegetarian dishes (or learn to cook yourself) buy frozen food without meat in it so when your family has something meat-like you can have that. Also, there are so many great fake-meat stuff out there, (especially veggie burgers, some of them are so much better than regular ones, also fake sausage is so good) After a while, you get use to the not meat stuff and you don't even miss it.
