Food that is served on a flat or slightly rounded plate is called a dish. We put different types of food in a dish to make it easier to eat and to keep everything separated. It's like having your own little section on a playground where your toys are. Just like how we need different toys to have fun, we need different kinds of food to keep our bodies healthy. Dishes can be simple like a plate of spaghetti or complex like a fancy salad with lots of different ingredients mixed together. So, a dish is basically a yummy combination of foods put together on a plate or in a bowl that we can eat.
