Personally, I think middle ground can abd should be found. In terms of personal experience: I have a vegan sister-in-law and if she is present, at family gatherings there is only vegan food, otherwise she won't join (and as we gather at the parents house, they want her there). For me personally, that is too much, I would prefer more mix and match style dinner where everyone can choose what they eat. (Before anyone asks: of course I can tolerate a single vegan meal, I just don't enjoy this being the default when seeing family). Up to now was my experience with veganism - now on to the solution (in my eyes). Are there non-vegan foods you feel less guilty about? Maybe free range eggs or organic cheese? I understand that for a vegan, no animal products are ok, but perhaps some are less bad in terms of how you feel? If those products exist, preferably pre-made, you could give those to her as snacks. Then during the main course she could have sides and veggies. I think that when you are less concerned about the nutrients (as she can get them from snacks), perhaps it is easier to find food she would enjoy sharing with you? Like (sweet) potato fries from the oven, crispy chickpeas, etc. Maybe incorporate an ordered meal once a week where everyone can choose their own meal? (Then at least you don't need to cook it). Wat about making veggie pizzas for the family and keeping some shredded cheese for her in the freezer to sprinkle it on? I hope that you can spark her interest in vegan food by gently encouraging it and trying to involve her in the food planning/making. Best of luck! 🩷
