I'm not too big on sweets typically and don't have much like that around to snack on. I will grab some lunchmeat (yeah, I know...) and cheese to snack on or peanut butter and crackers. I also like to snack on chips but don't usually buy them so they aren't an option too often.
Anything sugary that I can get my hands on, even if that means cold cereal (sometimes that's all I have around). Usually I have some sort of treat hanging around, often cookies although I bake them far less lately than I used to because of how much weight I've put on. I'm not much of a cracker/chips/pretzels kind of girl. If I'm out of treats or nothing looks good, then I'll usually cut up an apple but that is far less satisfying
Anything in the fridge/pantry that doesn't take work to make. Cereal, crackers, fruit, candy (I try not to keep it in the house though), cheese... I am not too picky when it comes to snacks, though if I don't stop myself I will eat all of the food in the kitchen...
Chocolate. I eat lots of fruits and veggies too. But if I'm just going for a quick 2 second snack, it's chocolate. If I'm hungry and want to get a proper snack, usually some sort of fruit. And I also really like chips. Right now it's kettle's honey dijon. But I'll only buy one bag once in a while, and it's always gone within the day. Chocolate I'll buy a few bars at a time, and can keep them in the house for about as many days as I have bars I don't eat cereal or crackers or have any other junk in the house. And I have to be careful of what I eat around DD since I don't let her eat any of that either. Right now she's okay with the fact that she doesn't eat chocolate, but has her "treats" (ginger cookies, raisins and dried cranberries are her treats.)
