Do eggs smell? I’ve never thought of eggs as a particularly offensive scent. “Rotten eggs” is an offensive odor but has a very particular connotation to me beyond just “eggs” (I.e. sulphur)

Ive always thought it was somewhat rude for people to bring fast food on board like McDonalds or a pizza as literally the whole plane would smell it. Any type of cold cut sandwich whether homemade or not would be fine. And I do like the chocolate idea for sharing.
