I’m not married to a vegan.
In fact, if you ask my husband if he’s vegan, or even vegetarian, he’ll (sometimes more quickly than I would like) say no. So, our specific dietary preferences weren’t a primary or deciding factor when we decided to date, get engaged, or get married.
However, while we don’t share the same dietary label, we can and do share good food (which, most often, just so happens to be vegan, since I’m the cook in the house).
And, therein lies the rationale to attend a speed-dating event just for vegetarians and vegans.
