Raw and Cooked Green Baby Food

This one is for all of those super smart mothers or babysitters out there. As many of you know, COOKED and his wife have a beautiful baby daughter, Ella. So far she only likes to eat fruit, squash, carrots and sweet potatoes. We have tried sweet peas and green beans, but she turns her face and refuses to open her mouth. Any suggestions on other green veggies to try and how to prepare them?
