This looks like such a FUN competition for Junior students! Have you seen the book, Piggity Wiggity Jiggity Jig Goes to Dad's Cafe, by Diana Neild and Phillip Webb?
This might be a great project to do in your class!
Or maybe you'd just like to do it for fun!
Either way, I bet you'll have fun designing your dish and naming it! When you have finished, your teacher can enter it in the competition for you. Entries close on 5 May.
