Getting homemade pizza right is a real art, I used to make it a lot when I was a kid and slowly perfected it over the years! One of my favourite things to do was to try different topping combinations from Asparagus and Spinach, to Feta and Rocket. One of the great things about pizza is that it's just so customisable. I also recommend experimenting with the tomato sauce as it can really enhance the overall flavour.
The main thing when you are cooking pizza is to make sure you have a really hot oven. Here is my standard recipe for a great pizza dough, I'm not sure where the original came from as I know it by heart!
