Cheesy onion pizza
A pizza without tomato? Believe us - buonissimo. Why not experiment with your favourite toppings?
Heat oven to 220C/fan 200C/gas 7. Heat the olive oil, then fry the onion and garlic until softened, about 5 mins. Season the passata with a pinch of sugar, salt and pepper.
Put the pizza base onto a baking sheet and spread over the passata, leaving a border around the edge. Top with the onions, sausages and, finally, the cheese. Cook in the oven for 10 mins until crisp. Scatter with basil, if using.
