-a little nutmeg
-^you could use pumpkin pie spice instead of cinnamon, nutmeg, and ginger if you have it on hand.
-sugar-free maple syrup (or regular, but i save the real stuff for pancakes and things because it's so expensive)
-additional toppings of your choice :)
here is my usual mix:
oiko's 0% vanilla greek yogurt mixed with pumpkin, maple syrup, cinnamon, dashes of nutmeg and ginger, and whatever topping i feel like (peanut butter, dark chocolate chips, or kashi go lean cereal for crunch)
