My sister say certain lettuces aren't vegan. The have animal products in them. She got mad that I didn't know that and refuses to come over again for dinner. It irratates me because I live a non-vegan life style, and she expects me to know what I'm doing. I rather he give me a recipe of hers than hoping she like one that picked that she thinks isn't vegan. I have all respect for vegans as I do for others but you want to f&$k with me 0 respect will be there for you. Can I get opinions? Does certain lettuces have meat in them? I get organic because she only eats organic stuff as well.
