Big glass of flavored seltzer water or a mug of Passion tea. Occassionally if I need something to actually have in my mouth I go for a hard candy or a small lollipop.
If I'm still hungry, I go for either a handful of nuts, a light starch, or a fruit. Granted I'm on a plan that allows only a certain amount of food each day, so I plan accordingly to that. Eating every 2-3 hours does typically keep hunger cravings at bay.
