A thoughtful non-supportive response; could it be like:

I truly believe plants have a capacity for feeling pain. Sometimes when I take a bite of an extremely beautiful leaf of lettuce I feel just as much a cannibal as when I eat a piece of chicken or fish. (not to mention eating flowers such as artichokes, nasturtium and violets)

(This point of vieuw ignores the problem of the animal factory issue with which I disagree completely.)
