Crunchy Low Calorie Granola Alternative for Yogurt

 I'm looking for something to add to my greek yogurt to make it crunchy.  I immediately though of Granola, but looking at the Granola at WholeFoods I see that most are pretty high in calories and sugar.

Can anyone think of a low calorie crunchy granola alternative?  I'm going to try some Kashi cereal clusters at 50cal\3g sugar for 1/4cup but I'm looking for something even lower.

I add walnuts and sometimes some Kretschmer Honey Crunch Wheatgerm also. The Wheatgerm is 50 calories and 1 gram of sugar per serving.   A serving is 2 tablespoons.  I usually only use one tablespoon.

I use sliced almonds.

I get Bear Naked FIT granola.  I believe that is what it is called.  It has 4 carbs per serving and I usually get it from Walmart supercenters.  I haven't been able to find this specific one anywhere else.  I also use  toasted sliced almonds, toasted unsweetened coconut, and berries.
