Cheeseburger Pizza

Caramelize the onions: Heat a large non-stick pan over medium heat. Add a drizzle of oil, then the onions. Cook, stirring occasionally, until softened, 4-5 min. Reduce the heat to low, then add the sugar and vinegar. Cook, stirring occasionally, until slightly caramelized, about 18-20 min.

Roll the dough: Meanwhile, cut the dough into two equal pieces. Sprinkle some flour on your counter. Using a rolling pin, or a long glass bottle (like a wine bottle!) roll out each dough into a rough ¼-inch thick circle (about 12-inch across.) (TIP: If you don't have a round baking sheet, roll each dough into rectangles to fit your baking sheet!) Place each rolled dough over two parchment-lined baking sheets and prick all over with a fork. Bake in the centre of the oven until the crust is lightly golden, 10-12 min.

Prep: Meanwhile, wash and dry all produce. Using a vegetable peeler, peel long ribbons from the zucchini.

Add the ground beef to the pan with the caramelized onions. Increase the heat to medium. Cook, breaking the meat up into smaller pieces with a spoon, until no pink remains, 4-5 min.

Assemble pizza: Divide the tomato sauce between each baked pizza dough and spread the sauce to the edges. Top with the beef and onion mixture, zucchini ribbons and sprinkle with the cheese. Return the pizzas to the oven and bake until the cheese is melted, 4-5 min.
