Frozen pizza is a pre-cooked pizza that is packaged and stored in a freezer. It typically comes in various styles, including thin crust, thick crust, and stuffed crust, and is available with a wide range of toppings such as pepperoni, vegetables, and cheese. To prepare frozen pizza, you simply remove it from the packaging and bake it in an oven for a specified time. This convenience makes it a popular choice for quick meals, as it requires minimal preparation and can be ready in about 15 to 20 minutes.
