Little Pea by Amy Krouse Rosenthal

Little Pea is happy.  There are many things he likes to do, such as roll down hills and hang out with his friends.  There is one thing, though, that he does not like, and that is to eat candy as the main course every night for dinner--which is what you have to do if you are a pea.  He struggles through, reluctantly swallowing not just one piece but five, in order to have his favorite dessert–spinach!  This simple story is a twist on the age-old admonishment that children everywhere hear each evening.
