Food for Tot

So, my son just turned 1 (yay!!!), But I am not really sure what I should feed him for lunch and snacks. Looking online doesn't really help and I'm unsure what is and is not okay to let him have. He has choked on food before, so I'm really afraid to give him foods like pb&j. He chews pretty well with 4 front teeth and 3 bottom teeth. Any ideas?
