The raw materials in these two dishes are quite similar, however, with the different cooking methods, they reveal the difference between the two regions. The left dish is Pittsburgh, which has large slices, and many potatoes as carbohydrates. The right dish is Woodland Hills School District, which is of smaller dices, and sweet potatoes as carbohydrates that is healthier than potatoes. The former represents Pittsburgh that the resources are aggregated together and not located evenly, and the school's menu is not that healthy. The latter illustrates that the food access are distributed relatively even in the area and the school's menu is healthier with fruits.

I guess, by looking and tasting these two dishes, people will get a direct and clear understanding of the food resources in these two regions and how healthy are the foods in the school are. And this might raise people's awareness of healthy diet, thus may improve the balance in the diet in the future.
