Try to find what that quote is based on.
For example, here and here and here I found they were misquotes for which I found original/actual quotes.
Gandhi could be difficult e.g. whatever he said might not literally have included the word "fork". Gandhi needn't have been writing in English, and many of these internet sound-bytes are a paraphrase/summary of what was actually said.
If you can't find evidence for the quote it would be interesting (evidence) to find a related quote of what he actually said. Did he ever say anything like it? Was it in the context of a political weapon against the British? Did he ever have anything to say about vegetarianism and animal welfare? That would at least let you answer with "plausible" or "implausible" (which is better than nothing), and leave readers a bit better informed about what he actually said.
