Put the bread end in the toaster for about 40 seconds to 1 minute.
Spread on the pizza sauce / puree / ketchup.
Sprinkle on the cheese.
Add the herbs if you wish.
Add a touch of salt & pepper.
Put under the grill / in the oven for 2-3 minutes.
(The easiest way to make this is to use either tomato puree or ketchup but I found I made this so much that I actually bought a small jar of tomato pizza sauce to keep in the fridge, which is so much better and makes it taste like an actual pizza!)
