As a Buddhist layman and a vegetarian, when faced with a piece of meat, should you choose to waste it or eat it?

It is not allowed to eat, but it is not good to waste it. If someone in the family eats meat, then just eat it. Some people eat meat and some are vegetarians. This is how the world is. You cannot ask your family not to eat. You are a vegetarian. Just don’t eat it. Or feed it to stray cats and dogs. We just try to make things as perfect as possible within our capabilities. For other things like this, you can read Layer Guoqing's book "Modern Cause and Effect Record", which is a collection of three volumes. When it comes to those who believe in Buddhism, it is like how to deal with certain things in life and work, and how to practice in a reasonable and legal manner in daily life, and deal with them according to circumstances. As a lay Buddhist, if we can't handle some small things in life well, it seems that belief in Buddhism has become an obstacle. However, if we grasp the basic principles, we can adapt to circumstances very well.
