Isn't it annoying when you find meat hidden inside dishes that should be vegetarian-friendly? A month or so ago, my family ate at an Italian restaurant where I ordered mushroom and cheese ravioli (one of the few dishes that didn't include meat). When I received the meal, I found pieces of bacon hidden inside.
