Step 1

Caramelize the onions: Heat the oven to 400 degrees (if you have a toaster you can skip this step!). Halve, peel, and thinly slice the onions. Heat a drizzle of oil in a large pan over medium heat. Add the onion and 2 teaspoons sugar to the pan and cook, tossing, for 6-8 minutes, until caramelized. Season with salt and pepper, then set aside.

Make the vinaigrette: mince or grate the garlic. In a large bowl, whisk together 2 tablespoons tomato paste, 4 tablespoons balsamic, 4 tablespoons olive oil, and garlic (to taste—start with a little and go up from there!). Season with salt and pepper.

Cook the burgers: Form the ground beef into 4 patties. In the same pan you cooked the onions in, heat anther drizzle of oil over medium-high heat. Season the patties on all sides with salt and pepper, then place in the pan and cook for 2-4 minutes per side, or until almost cooked to desired doneness. Top the patties with the mozzarella and Parmesan cheese, then cover and cook another 1 minute, until the cheese melts.
