So this post is inspired by the current top post on this sub.  I have a fairly similar situation and figured I will put mine out there. 

So I have been dating this girl for a few months and for the most part things have been going really well, except for our dietary differences. I grew up hunting and fishing with a meat heavy diet and she grew up vegan and we have both carried those diets into our adulthoods. 

When I cook things seem to work out fine, I cook the dish without the meat, serve it for her then add the meat in for myself. Or I just make 2 entirely different dishes.

But occasionally she will cook for me and will want me to try her vegan dishes. But goddamn is it gross. I am not sure I will ever understand how people eat tofu.

So recently she said she wanted to try and make something new. I told her that I will happily try it but that I wanted to bring over a venison steak so I would have something to make if I didn't like it. Because up to this point I haven't liked any of the dishes she has made (I didn't say that last part but she knows it already).

After typing that it sounds more dickish than I think it is so let me add that whenever I cook for her that I make sure to have an easy fall back dish that I can quickly throw together if she doesn't like what I made. Ultimately I think food is one of life's great pleasures and you should always enjoy what you eat.
