Place a deep skillet over medium-low heat. Stir in butter, sage and garlic. Meanwhile, bring a
saucepan of lightly salted water to a boil. Drop the filled raviolis into the boiling water, a few at a time, and cook until they float to the top, about 2 minutes. Drain the raviolis, and transfer them to the skillet. Turn the heat under the skillet up to medium-high, and cook just until the raviolis are infused with garlic flavor, about 2 or 3 more minutes. Sprinkle with chopped sage, more
black pepper, and extra Parmesan cheese to taste.
