Heat oven to 350°F. Lightly grease two 9x5 or 8x4-inch loaf pans. In small bowl, combine Parmesan cheese and walnuts; mix well. In another small bowl, combine cream cheese, basil and garlic; mix well.
Separate dough into 8 biscuits. Spoon 1 teaspoon cream cheese mixture on half of each biscuit. Fold biscuit over cream cheese; press edges to seal.
Dip each biscuit in melted butter; coat with cheese-walnut mixture. Arrange 4 biscuits, seam side down, in each greased pan. Drizzle any remaining butter over biscuits; sprinkle with any remaining cheese mixture.
Bake at 350°F. for 25 to 35 minutes or until golden brown. Immediately remove from pan. Serve warm. Store in refrigerator.
