Thats awful! You must feel absolutely sickened!
I had a similar experience, but from a well meaning friend who promised me it was that yves soy veggy pattie stuff. About halfway through my piece of lasaunya I started getting a really bad stomach ache. But my family friend was so happy I was eating the food that I thought oh, I guess I'd better finish it. I was almost heaving by the time I finished the food. Then to make matters worse this woman smiled at me and said "congratulations! you just ate beef! would you like another piece?" I was devistated!
That is my only experience with accidently eating meat. I was 13 at the time and had been vegetarian since 10. At the time I was living in an anti-vegatarian town. But now that I no longer live there and now am in a progressive city full of vegatarians I rarely have people get mad at me for my personal choice of being vegetarian.
I have always found that having a good comeback is the most beneficial way of changeing friends strong opinions. I've written a couple of them on here.
"When your vegetarian you don't get protein"
How many times a week to you eat pork?
friend: umm once every week or two..
How else do you get protein?
Yup, you can get protein through eggs, cheese, milk, enriched cereal, beans, lentils, nuts, soy milk, tofu, whole grains, and some other ways.
Yes, some vegetarians don't eat eggs, I personally still do.. But if I ever change that I will still have many ways to get protein without eating pork or any other kind of meat.
"Vegetarians are anemic because they don't get Iron"
What are some ways that you can get iron?
friend: beef, and other meats.
yes, that right. are there any other ways?
Umm enriched cereal?
Yes. Also you can get iron from beans, 77% cocoa CHOCOLATE!!!, Broccoli, green leafy vegetables, whole grains, like you said "enriched cereal", I also always take and additional preventative iron pill everyday that is specially formulated for vegetarians. I get 300mg of ferrous sulphate (iron) from the pill everyday. Of course it doesn't all absorb, but it helps.
I find those are people's two main issues with vegetarians. But just having a few responses under your belt can prevent a lot of heartache.
A few other issues to be prepared for if you are a new vegetarian or vegan. (you get lots of dumb questions, they may not even apply to your diet!)
And a few other vitamins.)
