What do you give your 6 month old to eat?

I'm always having a hard time knowing what to give my baby besides his breastmilk. Pediatrician told me I can start giving him Gerber and cereal which I have but he seems to be more interested what I'm having at the dinner table. I'm not very creative and I'm always in a hurry and have another child as well so what other kinds of food could I give my baby? Should I be worried that I don't give him a lot of solid foods? Is it necessary for him to start now since He has no teeth in yet by the way...suggestions?
