He's looking at your food like he wants to devour it, even when fifteen minutes ago, before the man in the truck handed it back to you, he said he didn't want any.

You're sitting on a bench, looking out at the rest of the park, and you can see him glancing over at it from the corner of your eye, feel his gaze on your food.

More than anyone you know how stubborn your boyfriend can be, so you know he's likely to never admit his hunger or how good he thinks your food looks. But it's getting a bit sad now... Maybe just let him have a bite?
