Raising a vegan baby

We would like to raise our daughter vegan (as long as she wants to be) but that means until she is old enough to have a say in what goes into her mouth, I’d like to nix any animal products as my husband and I are both vegan. We have just begun feeding her solid foods, but her pedi is already trying to push chicken and beef despite us informing her of our wishes. Does anyone know how to do this safely and healthily?
