<human>:  Is it okay to eat bread with some green stuff on it?
<bot>: Well, that would depend on what kind of green stuff it is. There are lots of different foods that have green coloration. Some of them are okay to eat, and some are actually quite toxic. Does this green stuff have bits of grass or wheat or chard in it? Or is it something more chemical? Like fertilizer? Please describe the green stuff more thoroughly, and then I’ll be able to advise you.
