Picky eater

My husband is hispanic and was raised with italian cooking parents. They ate mostly italian food. I am hispanic as well but we ALWAYS ate the food. Therefore, Im anamazing cook(tooting my own horn) there is tons of hispanic food he doesn't like, which in turn we have arguments.

He just ate 6 of my enchildas yesterday! But hated how I made the eggs this morning. I don't get it.

He's comfortable eating out every meal which we cant afford. I really would like for him to try new foods but he's set in his pallet.

Im tired of arguing with him about it.
