Todays lunch was simply tuna mixed with olive oil, salt, and pepper on whole-grain bread. I actually keep a mini-pantry of food in the office, and 3 ounce cans of tuna are always on stock. One is the perfect size for a sandwich with no leftovers to clog up the office refrigerator, and also fits the bill for an afternoon snack. Other foods I keep desk side raisins, nuts, pretzels, oatmeal, a couple cans of soup, yogurt, and cheese sticks (those last two, in the fridge of course). Here are some more office-friendly food ideas.
