S.M.
Try the "orange" veggies. A lot of my friends are earth-mama types who do the whole organic/vegan thing and their babies (range from 9 - 16 mo.) have responded particularly well to sweet potatoes, acorn squash, pumpkin, carrots, etc.
Basic recipes are pretty simple... put cut up veggies in a bag add a tablespoon of lemon juice and a light sprinkle of kosher salt and shake it up. Then roast in oven at 400 degrees for about 30 - 40 minutes (depending on the hardness of the veggie). Generally, these foods are for the whole family, but the baby portions get mashed and mixed with breast milk. I've never seen kids love veggies so much. I can't wait to try it with my little girl when she's ready for solids.
Good luck.
