What are your go-to foods to deal with cravings or being peckish?

I fully advocate healthy satisfying meals, but there's no foolproof way to completely avoid getting peckish in the afternoon after a rubbish night's sleep, or sugar cravings when work is stressing me out.

And I can never 'just have one' biscuit - if I start, I'll eat a whole pack.

When I'm feeling bored and peckish in the afternoon I usually turn to celery sticks because I can munch mindlessly without worrying about calories.

In the evening if I'm still hungry after dinner I'll make a massive plate of steamed broccoli and cauliflower with a bit of butter and salt.

Or if I can't stop thinking about sugar, I go for berries, or chocolate chip snack-a-jacks, or an iced latte with a shot of sugar-free flavouring.

I'd be interested to know what other people's hero-foods are, that they turn to when their willpower is fading or so they can stay on track without feeling completely deprived. It would help to have a few more ideas in my arsenal!!
