Here is a pizza recipe https://food-heritage-archives.com/2020/09/09/pizza/
Not only can you cook pizza on this, but it is a non-stick baking sheet as well.
I cook frozen mozzarella sticks, fish sticks, bake fish or chicken, broil grilled cheese sandwiches, roast peppers, and many other things on it.
When you clean it, just use boiling water. After a couple uses the stone will darken substantially, but it is natural and will not affect the cooking. I have had my stone for over two years and it is used at least once a week most weeks.
The stone takes a few minutes to get hot, though it holds its heat very well.
I found mine for less than $20 at Target, and there are plenty of options under the $30 range. Just make sure the one you buy can at least go up to 450 degrees.
