I do kind of get what the issue is, in that the meal option for a vegetarian is not as wide as for a carnivore.
I would like to point out that elsewhere in Europe, the USA and Australia you are really stuck for options. I recall a friend of mine that used to work for an airline, and was a vegetarian. She basically either ate just fries, or had to compromise and eat some kind of meat, otherwise she wouldn't actually be able to eat anything.
In the UK we do have a diverse array of cuisine available to us, so the options ARE there. Elsewhere they simply aren't.
If you love Indian Food, or Thai food or whatever, then that is likely to be the best places for you to choose from a wider selection, than in a restaurant that caters to mostly meat eating clientele.
As numerous as vegetarians are, they are in the minority.
I don't eat pork, so that rules out a ton of stuff when I eat out. My own mother picked some ham wrapped dish for her main course when she got married. With the ham removed the meal was worse than tasteless...
Problem is, for meat eating restaurateurs, that they often just think a vegetarian dish is one without meat, and that cheese etc is still acceptable, but for many of you, it is not.
I get your boredom, really I do, but tbh it's a choice you have made for whatever reason, and in general, hotels and restaurants ARE providing Veggie options, but perhaps in your eyes, not very imaginative ones. But at least there IS a choice.
Here's a challenge to all you veggies...
Give us the name/description of your fave veggie dish.
Then perhaps people will see what kind of food is desired. DH is a Head Chef, and I always tell him to make sure there is a vegetarian option on his specials board, I'd be delighted to get him to try new ideas..
