1. Preheat grill to medium-high.
2. Heat olive oil in a saucepan over medium heat. Add onion and garlic and cook until soft, about 2 minutes.

Carefully transfer mixture to a blender and process until smooth. Pour sauce back into the pot, cover and turn heat to low. (You can also just keep the sauce in the pot and use an emersion blender if you prefer.)

5. Flatten each portion and top half with mozzarella cheese. Place one burger on top of the other and press edges to seal.
