Could you help me design a balanced diet with everything the body needs?

I am trying to design a diet for me to follow, and could use a hand.

I am not trying to create a diet to lose weight for a week then quit, instead I am looking to create a balanced diet, that can fit in to a week long time table.

Can you think up any food ideas for a day, that include breakfast, lunch, dinner and a snack, and that still remain in the 1600 to 2000 calories range?

Thanks
