Ice Cream. Even though I'm more of a salty than sweet person, it's hard to beat ice cream. There's such a vast variety of flavors, toppings, and forms you can have ice cream. So you'd pretty have to dislike sweet things to not like ice cream. Chips have a variety as well but I guess I don't like they're texture.
Before they discontinued it, I used to (and still do unfortunately) LOVE the Mrs. Sara Strawberry Cheesecake Ice Cream by Breyers I think it was. It had diabetic coma in every bite. I love Ice cream. Man don't know what I do if I can't get a bit every now and then.
