if you have a freezer, frozen green grapes...deeeeeelicious and refreshing.
Green tea and edamame chips. All green snacks. :)

I know popcorn has already been brought up, but here's my twist: I make it at home ahead of time on the stovetop. The benefits of this are great: first, popcorn kernels are super cheap. Second, you can control the health factor, making it with olive oil, etc. Third, you can dress it up or leave it plain. I pre-salt the oil before adding the kernels, then once the corn is popped, I add a little butter and some nutritional yeast. You can do cheese powder, or a selection of herbs. You could even go sweet with some kettle corn recipes. After it's cooled completely, I transfer it to a ziplock bag, which usually lasts several days at the office.

A small piece of fruit! Because usually I am craving sweets for a snack.

Marcona almonds and a glass of port.

Great in the morning so you can get a head start on drinking before lunch. Great in the afternoon so you can pull through the last hours of work.

Smoke Almonds and M& M's {together!!}

@ therealchiffonade - make the olive oil granola - you will not be disappointed! it's like crack. i have everyone in my office hooked on it. i'm not sure i can keep up with the demand (or share any more!)

My list!

Mix of roasted/unsalted nuts: peanuts, almonds, walnuts, cashews
Sliced fruit/berries
Mix of crispy veggies: carrots, cucumber, sugar peas, celery, radish
Yogurt
Granola
Pretzels
Panda Licorice
I make batches of muffins and freeze individually and grab and go
Those Clif Kid fruit twisty thingies - Dood, these are good!
Annies fruit snacks - They're weird but deelish.

I also try to bring my lunch and on Friday's I adventure to the food carts in Midtown. YUM.

Popcorn popping banned in my office, too, but I don't mind - it stinks up the whole floor! I bring wasabi peas, tamari almonds, apple & cheddar cheese, banana and peanut butter (I put the pb in a tiny tupperware container), baby carrots and hummus, stuffed grape leaves (they travel really well), and string cheese. If it's a rough day I'll resort to dark chocolate or potato chips.

Ale.

Recently I've been packing a small (1 slice folded) peanut butter and fruit sandwich as a snack. Fresh blueberries are really good with PB, as are peach slices.

I also second the votes for dry cereal. It satisfies that finger-food crunch craving.

Lots of fruit. Granola bars. Babybell light cheese. Carrot sticks. Sugarsnap peas. Cut up red bell pepper. Greek yogurt with honey or jam or fruit or plain... I snack like it's going out of style! I love snacks!

I don't work in an office (I'm a massage therapist), so I don't have a set lunch break every day. Snacking gets me through my day without eating my fingers (which would be bad, since I need them to work).

Since i usually need to work through lunch:

1 peanut butter Nature Valley granola bar + 1 apple/pear/any other portable fruit keeps me going indefinitely..but absolutely MUST eat something yummy for breakfast :)
