Courtesy

Yes, this issue belongs in this cooking blog because it is important that you treat guests with respect to what they can and con not have.
You MUST know your guests before they arrive and what they like, what they do not like and what they simply must stay way from.
Although i truly eat and cook everything without dietary restrictions, i know that i will not use pork if i have someone who for whatever reason can not have pork.
Many of my recipes, chicken or beef can be substituted very easily.
What about vegetarian or even more restrictive, Vegan.
Yes, i can make a very good Vegan chili and making vegetables the center, corner and all of my meal is not beyond my grasp.
So if you are invited to my home, i will cook what is appropriate for you for us to share a meal together.
This is courtesy and essential in all manners of service.
