advice: a vegan at an omnivore thanksgiving
so, here's the deal. i'm newly moved in with my boyfriend, across the country from my family. since going to my mom's is sadly not an option, i hear thanksgiving will be at boyfriend's grandma's house. before i moved, every thanksgiving dinner at my mom's was a non-issue, as i'd just bring my own vegan stuff over and cook things i wanted to eat. no problem, no awkwardness.
i am not about to do the same this year. so, i don't quite know what to do. boyfriend says i should just bring my own (i'm assuming ready-made?) things to eat, that his grandma is pretty easygoing. i'm concerned about making a bad impression or insulting her and whomever else may be cooking the meal. but i'm also concerned that there won't be anything there i'll be able to eat. if i eat little or nothing, that would also be awkward, and insulting to the hostess.
anyone been in a similar situation before? what shall i do?
