It would be in the dairy section, and the grain section because of the bread and cheese. Cheese is made from milk, and milk is dairy!! Hope that helps!
Cheese Pizza belongs to the food group Grains, because it is made mostly out of dough (flour.) Pizza is not a healthy way to get your serving of grains though, as it is extremely high in fat and carbohydrates, yet low in fibre. It really should be placed in the Junk category of food groups.
It'd be in the Grains group, since a sandwich contains bread. It may also be part of the Meats group, as well, since there is turkey.
Meat, dairy, and bread.
cheese is dairy so it would be in protein
