In think the key thing is to make it obvious so you’re just being asked all night what people can and can’t eat. I would do cold buffet with almost zero cooking so you can have some fun too!
• green salad
• heritage tomato salad
• crudities and those gressini breadstick things
• dips including things like beetroot houmous
• a superfood salad - one or two of those quinoa pouches, baby spinach, toasted pine nuts, avocado, maybe roasted butternut squash.
• a tuna/bean/olive salad in vinaigrette for the dairy free/high protein types —and any passing pescatarians who come just to fuck with your head— There’s a nice one with fennel on Waitrose site.
• some quiches, things like cheese and caramelised onion so no ‘is it meat?’ questions
• individual dairy free/vegan quiche/tartlets (bought) for specific people
• a cheese board and
• cold roast gammon
• lots of crusty bread and a separate (ideally wrapped) gluten free bread basket/tub
• oils (decent olive, walnut) balsamic vinegar, good butter, a couple of (bought) dressings
then gluten free types can eat everything except bread and pastry
vegetarians can eat everything except meats and fish
dairy free can eat everything except cheese, butter and dairy dips (just check ham fir extra ingredients)
vegans have stuff to eat
depending on how much you like them/have time you could add
• roasted veggies - peppers, aubergine, sweet potato, courgette etc, done in advance
• charcuterie board
• things like olives, walnuts, grapes, dried apricots on cheese bord. Also chutneys and pickles.
• potato salad made with vegan pesto (for question avoidance)
pudding I would do small bowls of soft fruits (strawberries, raspberries, blueberries, peaches) with a bit of mint and choice of thick cream or mini ice cream tub.
if you’re feeling generous get some mini vegan ice cream tubs too
lots of rose, cold beer, iced water etc and it’ll be grand!
