@SleepyMaya @simsplayer818 @daikoyu and anyone else seeing this issue, could you provide a bit more information? For example, what events other than the weenie roast are affected? Is the vegetarian sim the host, or is a non-vegetarian sim hosting, and in either case, is the host doing the cooking?
Even if the party goal lists a meat dish, does the goal complete when a sim makes the vegetarian equivalent? If not, please have your sim try making the meat dish just in case the task isn't completing for some other reason; you don't need to save your progress.
I test the weenie roast event with a vegetarian/non vegetarian sim in a vanilla game and can confirm that tofu-hotdog count as goal (grilling and campfire). Was the campfire always so terrible in a vanilla game? This thing caused 3 fires in one event!
I only can confirm @simsplayer818 statement that sims ignore they food/allergies preference sometime in spice-event. After my *vegan* sim issue I never used this both traits again for my played sims. Generally, two traits slot are too much sacrifice with only 3 slots per sim available. I really wish they would give is a food dislike/like category. Would make things so much easier... as long they ignore food which they do not like.
Btw: the default recipe of marshmallow is not vegetarian safe because most use gelatine, so it doesn’t make any difference if it beetles of marshmallow, both are dishes who use ingredients from animals (a dead animal) and so not suitable for vegetarian sims
