>>40153011her explanation makes sense. She wanted stuffed crust pizza, but was too esl to know that stuffed crust was a kind of pizza and thought that stuffed crust was specific to pepperoni so she would order the stuffed crust pepperoni and then pick the pepperoni off. For some reason the jap word for crust is ear so she tried to directly translate it because she knows what the word ear means.
The whole peppaloni speech was due to her being a retard, not due to her not knowing english
