Cook ravioli according to package directions. In a large heavy saucepan, melt butter over medium heat. Heat 5-7 minutes or until golden brown, stirring constantly. Immediately stir in sage and salt; remove from heat.
Drain ravioli, reserving 2 Tbsp. pasta water. Add ravioli, pasta water and lemon juice to butter mixture; gently toss to coat. Serve with parmesan cheese.
