Healthy food.
I find unhealthier foods (although having been in treatment for anorexia nervosa [now weight-restored] for almost 2 years, they are very big on 'there's no such thing as good or bad food, everything in moderation') are far more satisfying when they're a rare occasion. Things like Christmas, a few days of feeling like it's constantly unhealthier, richer foods, or more chocolate and snacking, a few days of that and I feel like I just crave fruit and salad.
And I feel like the idea of fast food is always more appealing than it actually is in reality a lot of the time.
