My new work friend and her husband and kids are coming for lunch at mine next week. They are Muslim. Obviously I won't serve alcohol or non halal meat but, any catering advice in terms of things to avoid? Also I hug her on greeting (outside of office) but should I not hug her DH / should my DH not give a kiss to her on greeting? (We are not English and we are usually fairly tactile). Sorry for this lack of sophistication but I'd rather ask than cause embarrassment or serve food they can't enjoy.
