Am I the Asshole for Hiding Vegetables in My Boyfriend's Food?

I, 28 female, have been with my boyfriend, 36 male, for a year. One of the first things I noticed about him was that he never really ate vegetables. He would sometimes eat them if we were out at a restaurant and they came as a part of his meal. Six months ago I started hiding vegetables in my cooking. Am I the asshole? Can I answer?
