Kili - Chips, battered sausage (he no longer likes fish because of the barrel incident), no peas (because that's elf food), washed down with ale, cider or mead.
Lyndheid (I've yet to do her profile), traditional Sunday roast, with all the veg but cabbage and sprouts (yuck....), stuffing and Yorkshire pudding, washed down with tea.
Huldrika (I've yet to do her profile), berries (all kinds, blackberries, strawberries, raspberries, gooseberries) perhaps in pie form, but it doesn't matter, with honey cakes (or ANYTHING with honey), cheese. As she's a Beorning, you'd not want to take her to any establishment that wasn't vegetarian, though vegan would probably be the safest bet. Anything with meat would send her into a rage.
