I live with a vegetarian despite being an omnivore myself. I've got used to most of my meals not having any meat and have found it has virtually zero impact on my enjoyment of food - because generally great flavours are because of good seasoning, herbs & spices and deep rich sauces etc etc. You really don't "need" meat and I'd be happy enough if I never ate meat again.
I also increasingly think that eating less meat is better for my health and the planet - win win.
However it is very convenient if I go someplace where meat is one of the only decent options, or if vegetarian food is not done well. I can just pick a meat dish, no drama. And it's such a rare thing for me to eat meat, I know in the grand scheme of things it won't have a big impact.
Why can't vegetarians do the same as me and just accept that eating meat once in a blue moon for the sake of convenience and enjoyment will not "undo" all the good that many months of not eating any meat at all has done.
Instead they becoming obsessed with the label of "vegetarian' and having to live up to this ideal. And tying themselves up in knots in certain situations in order to avoid meat, especially if it is some tiny meat-derived ingredient that is causing the issue. It would just be easier all round to relent - just for one meal.
I understand if you are a hardcore ethical vegetarian who loves all animals you will never eat meat - but that isn't typical of most vegetarians these days is it?
I guess I'm just not such a black and white thinker about these things, and like to embrace the grey!
