Lunch

How do you communicate with a non-verbal 2 year old about what they want for lunch? We ask J everyday and she just looks at us like we are just supposed to know. Of course she doesn't typically complain about what is offered to her for lunch. (1/2 a grilled cheese sandwich and a banana or a toddler tray meal) She has some picutre cards for communication, but we are just getting started with that. At least there isn't much of a fight with her about food. Yet, anyway.
