Beans are very good for baby. High in protein and other stuff lol. I use mainly black beans, but have also given Sol garbonzo beans (aka chick peas), butter beans, navy beans, etc. Chick peas seem to be a favorite, just be careful as they do have a rather hard outer layer.
My favorite bean recipe:
A sort of Paella
1 can diced tomatoes
Measure out how much broth you need for cooking the rice (look for the amount on the rice instructions). Pour broth into a pan along with the other ingredients. Cook according to the rice instructions.
This recipe is very flexible. You can add in as many ingredients as you want and whatever ingredients you want. For feeding the little one though, be sure to blend it up before feeding him/her.
