Parenting

one - you can puree vegetables and add them to pizza sauce, spaghetti sauce, hide in casseroles - whatever they might eat.

Two - if you don't give them anything else - you have no junk in the house - you only offer them what you want them to eat, then, when they get hungry enough - they'll eat it.

Sounds harsh, but if they have no other choice, they won't starve themselves. They'll eat.

I grew up being called "Picky Eunice" (a southern term). I didn't eat much of anything. I was determined my kids wouldn't be. They were all allowed to have a couple of foods they could "refuse" - after all the smell of sauerkraut or rutabagas to this day make me nauseated - but basically - eat what you're given or go hungry. Doesn't take long.
