Catalina's Supermarket's Pizza - Western @ Santa Monica

Every time I have ever eaten a slice of pizza I have always next eaten another slice. I had a Big Mama’s & Papa’s a few weeks ago. I ate 4 slices of their large pie (18" is the “Large”, there). Then I had eaten enough food for dinner. I felt full.

I tried Michelle’s Pizza at Catalina’s Supermarket a while ago. They quarter their pies and sell by the slice @ $2.50 per slice (veggie pie). One slice and I had a meal. The size of the pie is pretty much the same. The thickness, too, with the same ingredients: cheese, sauce, onions, bell peppers.

Does anybody know why their pizza is filling in a way no other pizza palace is? A secret ingredient or something?
