"Depends on if you're looking for a short-term or long-term stay in your prison," Andy said from the doorway. "If it's short term I'd say you can eat whatever the taste buds on your tongue will appreciate. If you want to stay healthy for the next decade you may want to include lots of fruits, vegetables and whole grains in your diet." He walked further into the kitchen, went to the coffee maker and pushed the button; he always prepared it before going to bed so he wouldn't have to deal with that in the morning. 

"It comes down to this: we need nutrients from foodsources, proteins to repair and maintain the body and carbohydrates and fats for fuel." He tapped on the bread. "This is a source of carbohydrates. Cheese and meat, like the salami, are sources of proteins and fat, fruit like in that bowl also deliver carbohydrates. There are also micronutriets that we need for various reasons, but I'll give you a book that you can read if you want to know the finer details. For now I suggest you try and see what you like and you go from there. Some food needs to be cooked first though." 

The kitchen filled with the scent of freshly brewed coffee, a scent much welcome to Andy, who grabbed a mug from the cupboard. "Coffee?" he asked his guest.
