I am not a vegetarian (and would never be a vegan) but I always cook healthy. Years ago, I started serving one veggie dish per week. I have lots of great recipes.
Whereas I still like meat, I am finding that I am liking beef less and less. I eat smaller portions of beef. I would rather have chicken or fish at a restaurant. So, I do understand how you might be losing some of your taste for meat.
That being said, I have a story for you about our daughter's, and our, favorite nanny, Holly. Holly became like a daughter to us and a sister to Jen. Holly was a vegetarian. She is also Mormon and she went on her Mission to Hong Kong. Her host family served meat and she ate it because she was in their house with their customs. After she returned, she never really went back to being a vegetarian which is a good thing because she married a nice guy whose middle name should be beef!
