You went to bed hungry, lol? Well, seeing as I'm avoiding work... let's just read into it a bit. Maybe the chicken sandwich represents freedom (okay, I'm laughing here, but bear with me, lol). But you know, free as a bird, and eating it means taking that freedom into your being... and maybe you watched Orange is the New Black season-1 about the chicken - that definitely represented freedom and a better life. So the Asian girl is you, and she represents the more refined, dainty, controlled aspect of yourself - a part of yourself that stands in the way of truly granting your ex some aspect of freedom that you sense he needs. Perhaps it's your forgiveness that you're withholding, or you're ambivalent about allowing him certain freedoms.

...I'll never think about a chicken sandwich in the same way, lol.
