Hi Kristy Lynn,
I'm in a similar boat (I'm vegetarian and not willing to eat fish or meat). One thing I tried was incorporating different proteins into different rounds: For the first round, I allowed beans but no soy products (specifically garbanzo, black, and kidney beans, which I cooked from dried myself). The second round (i.e. the next year) I allowed soy products (specifically tofu) but no beans. That way I could get the experimental/information benefits of Whole30 without having to compromise my beliefs.
Hope this helps!
