Eat two cheeks is an adverbial phrase of mode. It is made up of three terms respectively: verb in infinitive (not personally) cardinal numeral preposition and plural masculine noun. It is a cliché, without reaching the proverbs or saying, while it rubs it in its meaning. That is, eat very anxiously, with his mouth full, without pausing and with gluttony or greed.
