Personally, I don't give finger foods until they can put it in their own mouth. At that point (I do TW) I use the baby puffs that are kind of like dry cereal but disolve in their mouth and are made from fruits and veggies - like these - https://www.toysrus.com/product/index.jsp?productId=4368744
On a side note - babies don't need teeth to eat solid food that needs chewing, they won't get their molars until they're a toddler anyway.
