Use an old monopoly board covered in plastic wrap and line up town house or club crackers (the rectangles) on each space. Top with a fruit or vegetable of the right color. Use a bowl of dip for the chance squares or more veggies. 
Checkerboard chicken salad sandwiches are made with white or wheat bread . . . the filling on these was all the same although you could alternate it also. After making the sandwich just lay them on your board (this was a marble board so I wasn't worried about cutting it) and cut with a sharp knife on the lines. Lay them out alternating and then use olives and grape tomatoes for the checkers (on toothpicks). 
Obviously you could do better on a dice cake than I did (I was out of time) but it was a cute idea if had been executed a little better. I also taped monopoly money to the cups with a few of them labeled on the back for door prizes. Use yatzhee cups and other board game accessories for candy holders and decorate with game boards, twister mats, etc.
