Pureed meat for babies?

My pediatrician said it's ok to start feeding my 6 month old small amounts of meat. She recommended not buying baby food meat b/c it's actually very little meat and lots of additives/preservatives. She said to puree plain meat at home, or even lightly salted/peppered meat that we cook for dinner. Many people I've talked w/ said this is way too early. I haven't given any to her yet. What's your opinion?
