Any insight on what we might expect if we select the VGML on SFO-SIN (UA29, so midday departure, evening arrival)?

Wife is fully vegetarian and mostly vegan, though really tries to avoid direct eggs and dairy (ie, she won't eat scrambled eggs or drink a glass of milk, but will occasionally eat things with minimal amounts of these ingredients). She's debating whether to do a VGML or AVML for this flight. I assume the AVML is likely to be Indian-style (I know we've seen a Thai-style curry before, but I think only once on PE on EWR-SFO). Had some not great options on other carriers VGML before (ahem....AC), but I'm not sure she's ever tried on UA.
