My kids weren't big on protein either at this age, so I added black beans or other beans to their veggies. They both loved that and mixed in with veggies, they would just eat them up. I didn't do baby good at this late in the game, but all kids are different. Like the others have said, try a grinder to get the food you are eating to the right consistency for him.
My older son goes through phases where he doesn't want to eat meat, then not vegetables, then back to meat. I just sit him down with whatever he is protesting this week first and let him have what he wants after he's done with the first course. You may not believe it, but after a few tries your little guy will get the hint - even at this little age.
