I make Pizza all the time and it's incredibly easy.
The tomato sauce I use is very simple. All I do is finely chop a medium sized onion, gently fry it then add a tin of tomatoes gently reduce it a bit and season to taste with Black Pepper, Salt, Sugar, Oregano & Basil, then blitz it. I make a lot then freeze it.
It's not authentic but I gotta admit that I don't think I'd enjoy the simplicity of the authentic Italian pizza.
The pizza base is whatever you want it to be but I tend to make the one that came in my bread maker’s recipe book.
As for toppings I like to use that Dry block of grate-able Mozzarella cheese and Strong Mature Cheddar then I go nuts and add Spicy Sausage, Pepperoni, Peppers, Sweet corn, Bacon and if no one's about Pineapple.
