Hi and welcome!
I made syn free pizza for the first time last night and they were so yummy!
I used Asda's whole meal bread mix, which I made up using the instructions on the pack. You can use 60grams of the dough as a HEX B for your pizza base.
Just roll it out into a pizza shape, I would have rolled mine out more thinly then I did on refection to ensure the whole pizza is cook property.
For the pizza sauce I used one tin of chopped tomatoes, and table spoon of mixed herbs, loads of garlic and two table spoons of tomato puree. I mashed it up and then cooked it on a medium heat for 5 mins.
Then just spoon some onto your pizza base, add your toppings, I used cooked chicken breast, and then sprinkle on your cheese, which is your HEX A.
Then cook in the oven. Mine took 20 mins on gas mark 9, but my oven is awful!
I batch made the dough, which you can freeze apparently and stored the spare sauce in my fridge. I am going to make a few pizzas tonight and bring them for lunch this week!
I hope this helps
