The problem with citing Scripture to support a position (e.g., veganism) is that there is always another, equally valid, section of scripture that supports an exactly contrary position. In this case, you'll want to take note of Genesis 9:3: "Everything that lives and moves will be food for you. Just as I gave you the green plants, I now give you everything."
Of course, both citations are out of context, but the point is that you cannot pick and choose what parts of the Bible to accept and what parts to reject.
