A lot of Greek yogurt is gelatin-free (not Yoplait's version, but Yoplait's version isn't very good). Honestly, good yogurts tend to be gelatin free. And you might want to try reading the ingredients list on store-brand yogurt. The Meijer-brand yogurt, for instance, is gelatin-free. I usually get a tub of the plain yogurt (I LOVE Fage Greek yogurt, but I'm too poor to afford it regularly), but I think even the Meijer-brand individual "light" yogurt cups are gelatin-free, which is unusual. But if I recall correctly, they thicken it with starch instead of gelatin.
