  1. Preheat the oven to 400 degrees F.
  2. Rub down each mushroom generously with olive oil.
  3. In a large nonstick skillet over medium heat add all of the onion slices, butter, and sugar. Stir gently and frequently until completely tender, about 8-10 minutes
  4. Add in the finely chopped spinach and sauté for another minute.
  5. Stuff the mushrooms full with the tender onion and spinach mixture. Season with salt and pepper.
  6. Combine the Parmesan and mozzarella cheese in a small bowl.
  7. Top each mushroom evenly with the cheese.
