Introducing solids?!

My son just turned five months on the 12th he started rolling over and sitting up at four months old, he was showing interest in the things I was eating and drinking so at five months he tried carrots peas green beans and applesauce he loves them all but I have a question… How do I start him on more solid solids like eggs for example I’m afraid he will choke how do I know when it’s OK to give him something more solid than puréed fruits and veggies?!
