Start by mixing up all your pizza sauce ingredients in a bowl.
Preheat your oven to 200C (fan).
Wash and cube your sweet potato (I tend not to peel but you can do if you prefer)
In a bowl, mix your sweet potato cubes with a little oil, salt and pepper (a tiny bit of paprika too is optional)
Place them on a baking sheet alongside a green and yellow pepper. Drizzle the whole peppers with a little oil. Then place in the oven for about 25 minutes. After this time all should be cooked, but just check.
Remove from the oven and allow to cool a little before opening up the peppers and slicing them into strips. (once sliced, ensure the peppers are not too wet and excess moisture is squeezed out of them – I usually do this with kitchen roll).
Spread a layer of tomato sauce over your pizza base.
Sprinkle over a generous amount of mozzarella (or dairy free/vegan cheese).
Place your slices of pepper and chunks of sweet potato on the pizza.
Slice up some black olives and add these too.
Pop in the oven for about 10 minutes.
Remove from the oven and serve with a handful of rocket on top. Enjoy!
