Our little one made this Paper Pizza at story time at the public library the other day and I thought it was so cute I wanted to show you all. The story time lady read several pizza-related stories and then had the kids make their own paper pizzas to bring home. The kids really enjoyed this project and I think it would make a great activity for a pizza-themed kids' party.
They gave the kids paper plates and a brown crayon to color the "crust" (our daughter skipped this part), then a paper red circle "tomato sauce" to glue down, shredded yellow paper "cheese", as well as paper mushrooms, pepperonis, and meatballs. After the pizzas were done, the kids took them home in actual pizza boxes which was the perfect finishing touch to the project. These brand new boxes had been bought ahead of time at the local pizza shop for a few cents each.
I don't remember the actual books she read before the project, but I've linked some cute-looking pizza stories here (affiliate links):
