Cheeseburger-Style Bacon Pizza

In a large frying pan, heat a drizzle of oil over medium-high heat. Cook zucchini, sweetcorn and diced bacon, breaking up bacon with a spoon, until golden, 6-7 minutes. Transfer to a bowl.

Return frying pan to medium-high heat with a drizzle of olive oil. Cook garlic until fragrant, 1 minute. Add tomato paste and the water. Simmer until slightly thickened, 1-2 minutes. Stir through the butter. Season with salt and pepper to taste.

Spread pizza sauce evenly across the pizza bases using the back of a spoon. Top evenly with baby spinach leaves, bacon, corn and zucchini. Sprinkle with shredded Cheddar cheese and sesame seeds. Place pizzas directly on a wire rack in the oven and bake until cheese is melted and golden, 10-12 minutes (use two wire racks if your pizzas don't fit).

TIP: Placing the pizzas directly onto the wire racks helps the bases crisp up. Little cooks: Take the lead by spreading the sauce over the pizza bases and adding the toppings!

While the pizzas are baking, wipe out frying pan and return to medium-high heat with a drizzle of olive oil. Cook onion, stirring regularly, until softened, 5-6 minutes. Reduce heat to medium. Add the balsamic vinegar, the brown sugar and a splash of water and mix well. Cook until dark and sticky, 3-5 minutes. Transfer to a small bowl.
