My dd won't eat meat either...but will eat pasta with sauce, so I saute' ground turkey and add it to the sauce.....it's so tiny (I chop it up into nothing!) she doesn't notice. Also, she will eat stuffing, so I make chicken and cut it up teeny tiny and mix it into the stuffing. Then i make little balls out of it and she calls it dumplings!!
French toast is a good way to get some egg into her, too...since she won't eat eggs at all. I throw some vanilla into the beaten egg, and some cinnamon...she loves it!
I have to be very careful with cheese, since it constipates my lo, but sprinkling a bit of parmeasean on pasta can give an extra gram or two of protien!!
Good luck!!! Get sneaky!!
