You're not that hungry. You really shouldn't. You just had dinner and yet... you can't resist. You didn't go looking for it, but when your eyes caught sight of that jar in the fridge or that loaf on the counter you just had to have a bite.
These are the foods we just gotta eat. Like that bad boy you kept falling for even though your head said "don't," these are too good to walk away from. You pick the victim, we'll send the temptation, one per month.
