picky eater toddler

Ok so my son (2.5) only eats a handful of things. Such as grilled cheese, pizza, spaghetti, mac and cheese. I guess anything cheese. Im worried hes not getting his veggies and fruits in. Occasionally he eats apples but rarely. I try sneaking veggies in or giving him kale chips but I wish he had a taste for healthier foods . eggs, fish and yogurt are the only healthy things he likes but only on occasion. Will he eventually grow out of this picky eating ? Should I wait until hes hungry enough to eat a good meal? I think he would starve without his go to meals ?.
