Could you make something like homemade hummus? It doesn't need tahini, just soaked and cooked chick peas, pureed with a little fresh lemon juice, a little olive oil, and some seasoning or flavor (curry powder, lemon pepper, salt, spinach, sun dried tomatoes - there's a million ideas online) served with pita chips. You could do a different hummus once a week for about a year. Or a homemade ranch dressing (again, recipes online galore, with no sugar) with vegetables.
Or, don't do food at all. You could do a simpler version of Elf on a Shelf, where a little toy elf gets posed in funny situations in various places. Instead of an elf, get something that's relevant to your area. For example, if you were from Green Bay with the famous cheeses, you'd get a little plastic or felt mouse. For Texas, maybe an plastic armadillo (look in gift shops). You get the idea. Hide it or pose it or let it hold up a silly sign.
Make a "stress buster" basket with those squeezy balls that you can use to relieve stress, or smooth stones that are soothing to feel, or little things to play with like those magnets that you can build into shapes. Just google stress busting toys. No need to have large ones, just ones that can fit on small shelf. Challenge everyone to choose one toy and give their fingers a break from the keyboard for 5 minutes. Change them every month or two.
