Combine the dry yeast, 1/2 teaspoon of sugar and 3/4 cups of lukewarm water. Mix a little and let sit for 6-8 minutes.
Combine 1 3/4 cups of unbleached strong plain bread flour with 1/2 teaspoon of salt in a bowl or food processor.
Pour the water combination into the bowl (or food processor) and mix until ready to knead (around 30 second in a food processor). If using a bowl, mix with a spoon, and your hands until you have a neat ball.
Prepare a lightly sprinkled surface with flour. Turn out dough and knead for around 2-3 minutes. Lightly cover your finger tips with flour if the mixture is a little sticky.
Roll out by hand for a 12'' base.
Place in 12'' lightly oiled oven pan. Press out dough to form a slight lip.
Spread your tomato puree or tomato sauce on top of the pizza dough. Then carefully arrange all the other toppings on top of the paste/sauce, putting the goat's cheese on last. (Or the mozzarella cheese if using.).
(Note - if you wish to caramelise your onions first, fry them in a couple of teaspoons of olive oil and a teaspoon of balsamic vinegar until glazed, soft and slightly sticky. Ready made Onion Confit or Onion Jam also works very well.).
Cook in a preheated over 250°C/495°F for 8-12 minutes (times may vary based on different ovens. Fan assisted oven will be quicker!).
Remove from oven, slice and share with your favourite friends and/or family members, keeping an extra slice for yourself!
