digging in lettuces etc??

They'll just rot down, so no problems.

Generally you're OK, just avoid anything diseased.

I believe the only thing you should really avoid putting in compost bin is anything with blight, ie infected toms or spuds
If im wrong someone will correct me but you should be ok

hows this for a worm feeder ,       cut a 6" or 4"plastic waste pipe about 30"long stand it in the bed you want to feed so that 6" is in the ground and 24"standing up,     fill it up with your waste veg and put a cap over the top   (this could be a bit of cloth or sacking with a elastic round)      the worms will go in the tube to feed and go back out and spread the good stuff around and they will then use it as a feeding station when they are hungry .
just take off the top and refill put top back on to keep the flies off
