My oldest son who is now 3 was a late teether as well. He got his one year molars the week of his 2nd birthday. I've heard the longer it takes to come in the better they are spaced in the mouth (not sure about that though). Anyways, there are tons of things you can start feeding him now, and the sooner the better. The longer you wait for table food the harder it will be to transition.
Canned vegatable and noodle soup (Progresso is wonderful) All the veggies are so soft they mash well.
Tofu - I don't eat it myself by Jack loved it and it helped get him some protein
Canned pears, and peaches
Oscar Mayer shaved turkey - my 1 year old eats half a turkey and cheese sandwhich as long as it's proccessed cheese and not real cheddar. I just cut it up really small.
Basically anything you can put in your mouth and smash on the roof of you mouth with you tounge is fine. You will be surprised how much they can eat!
