Can you eat cereal off a plate?

Each day as I threw away multiple styrofoam tableware, I challenged myself to combine, consolidate, and try to reduce how many different types of styrofoan containers I was using. Some mornings we had pancakes, which required a plate, cereal, which required a bowl, and then a drink, which required a cup. The thought of using just the plate baffled me. That's not possible to put my pancakes, cereal with milk, and gatorade all in one container. Why?
Dimensions! Certain shapes and dimensions determine what we can do and the forms of containers invented. A flat object is used for certain types of food while a cylinder is commonly used for liquids. Sometime try to use a shaped piece of dishware that isn't meant for the type of food you're eating!
