Green Bean is Not My Color

My once "eat anything" baby has now turned into a "won't eat anything unless it's banana flavored" baby. I was literally wearing green beans today because he spit out every bite; actually, he would start spitting before I even got the spoon out of his mouth. I just combined the bananas and green beans on one spoon, and he gobbled that right up (sounds yummy, right?). Anyone have any creative ideas to get a now somewhat picky eater to eat? (to tell me your idea, just click on the word "comment" below the post)
