Pretend he’s an adult at a dinner party. He didn’t get to choose the menu, but he does get to fill his own plate. Let him spoon out his own pasta, put his own sauce on or not, sprinkle his own cheese on top, and grab some carrots and string beans on the side for crunch. Or if he’s too young to handle the serving spoon, at least he can ask you for what he wants and guide the amounts he gets. It’s a great opportunity for a kid to practice autonomy.
