Prepare the pizza dough in advance so that it's shaped and already had the second prove before beginning. Make sure the onions and tomato sauce are ready.
100 ml tomato sauce, 100 grams caramelised onions, 1/2 batch spelt sourdough pizza dough
Preheat the oven to 240°C (460°F).
Top the dough with tomato sauce, followed by caramelised onions in an even layer. Add the apple, followed by the mushrooms, covering as evenly as possible.
1 large apple, 70 grams mushrooms, 100 grams caramelised onions
Drizzle the top of the pizza with olive oil and add a sprinkle of salt.
1 teaspoon olive oil, Sea salt
Bake for 13-15 minutes, or until golden brown.
While the pizza is in the oven, cook the kale. Heat a large frying pan over medium heat and de-stem the kale, tearing it into small pieces. Mince the garlic.
120 grams fresh kale, 3 cloves garlic
Once the pan is hot, add a drizzle of olive oil, followed by the kale and garlic. Fry for 2-3 minutes, or until the kale has wilted. If you want to, deglaze with some balsamic vinegar.
Remove the pizza from the oven and top with the garlic kale.
Slice into triangles and serve immediately. Leftovers will keep well for a day or two in a sealed container (I always simply store on the baking sheet, in the oven). To reheat, use the oven rather than the microwave.
Notes
If your oven can't reach such a high temperature, simply preheat to as high of a temperature as it will reach. Even at 200°C, you'll still get a good pizza - but it will take a longer time to cook.
