There have been similar posts in the past, and probably there is no good answer, but I'm still looking to you chowhounds for some help. 15 months ago my friend was at his folks house for dinner before taking them to the airport for their annual vacation. Not-so-evil-stepmom announced that dinner was eclectic because she had used up all the perishables before they left - a very scary statement if you have ever seen the inside of not-so-evil-stepmom's fridge. After years of suspect meals my friend took a deep breath and managed to consume most of what was on his plate. OK, you guessed it, after dutifully dropping them at the airport, my friend spent most of the night doubled over the toilet with a mild case of food poisoning. In the intervening 15 months my friend has managed to avoid eating anything that comes out of that kitchen. They have not been in the same place or have gone out for each of the subsequent holidays, and at other times my friend makes sure he has a late lunch or finds another excuse not to eat when he is there at mealtimes.
Now the problem is that my friend's sibling and family (spouse, 2 youngish kids) are coming for two weeks vacation, and not-so-evil-stepmom has planned family dinners for several of those nights. I have two questions: 1) How does my friend avoid eating there? 2) Does he warn his sibling and family not to eat any food they haven't themselves brought into the house and/or cooked themselves?
