1. Preheat oven to 475 degrees Fahrenheit. (If your pizza dough is not already baked, sprinkle a piece of Gefen Parchment Paper with cornmeal. Roll your dough very thinly. Transfer parchment paper to a heavy baking sheet or pizza stone and bake for six minutes.)
2. Heat two tablespoons olive oil in a sauté pan over medium-low heat. Add onions and sauté until golden, about 12 minutes.
3. Brush pizza crust with olive oil. Sprinkle with coarse salt, a few grinds of fresh pepper, and fresh garlic. Spread onions on crust.
4. Tear slices of fresh mozzarella and place around pizza. Drizzle with truffle oil and bake until cheese is melted, about five minutes.
