In twilight at the lunchroom you think Edward Cullen throw something on his plate at the table abut what did he say why did he say whatever he said andthrow whatever he threw?

i think edward threw some Pizza, but i am not sure, and i think he threw it down because he was pretending to eat but instead he threw it down. in the books edward and Bella eat lunch together a lot and edward eats some pizza, i am very sad that they didn't put that part in the movie
