What is your junk food weakness?

I imagine everyone must have a food that they know they shouldn’t eat, but sometimes temptation is too great. What is yours?

For me it’s definitely bread. Any variety, but especially white breads. My family went out of town for a few weeks, so my husband and I took home the food from their house that was likely to spoil before they got back. Including a loaf of italian bread. I am so tempted to eat a slice.. but I know that if I do that I’ll end up eating the whole loaf by the end of the week.
