Do you have a toaster at work? One of my favorite snacks is a piece of toast or a toasted English muffin, a drizzle of olive oil and half an avocado smooshed onto the bread with a fork, with a tiny sprinkle of salt. If you don't have a toaster, you could try crispbread or flat bread instead.
Also consider changing up your favorites a little. Instead of always carrots and hummus, try some green pepper strips and broccoli and celery and snow peas and cherry tomatoes. Instead of always hummus, try some low-fat ranch dressing, or tzatziki or garlic-yogurt dip.
Several months ago, I was searching for healthy snacks, because I have the same problem of getting stuck in a rut, and came up with this list. Maybe there's something here that you would like. I don't do Weight Watchers, so I'm sorry I don't know how many points these would be.
