Anna's Pizza Meatball Sub

In West Covina California by the Edwards 18 there is Anna's Pizza. Oddly, Anna's Pizza is best known for their Meatball Subs which have a lot less sauce than normal meatball subs but are served toasted and hot. 

Now Grandma from Sicily would not be impressed because Sicilians like more herbs in their sauce. I, on the other hand, have been craving this thing since I had one, and will have another some time soon.   

I don't know what it is about these, but they are great.
