Meanwhile, melt butter in a saucepan over medium-low heat. Add onion and garlic, then cook, stirring, for 5-6 minutes until softened. Stir in sour cream, cream, mustard and parmesan. Season. Remove from heat and cool completely.

Spread half the cooled cream sauce over 1 Lebanese bread, then top with half the beetroot, kumara and potato slices. Scatter with half the rosemary leaves and tomato. Season. Repeat with remaining Lebanese bread and toppings. Drizzle each pizza with 2 teaspoons oil, then place on trays and bake for 15-20 minutes until golden and crisp. Drizzle with the balsamic glaze and serve immediately.
