Husband is a picky eater

I’m at a loss for my creativity in the kitchen when making supper my husband is sooooo picky he doesn’t like melted cheese unless it’s on pizza, he won’t eat vegetables unless they are cooked carrots, he doesn’t really like chicken, he doesn’t like milk, mayonnaise, mustard. It’s so hard so I resort to pasta and tacos and salmon, but I’m tired of cooking the same three meals over and over again.
