In a medium mixing bowl combine cream cheese, Alfredo sauce, and 1/2 c. mozzarella cheese; stir in chicken until all ingredients are thoroughly combined.

Spoon into oven-safe casserole dish or baking pan.

Top with remaining 1/2 c. mozzarella cheese and 1/2 c. Parmesan cheese.

Bake at 350 degrees 25 minutes; then broil 3-5 minutes until cheese is golden brown and bubbly.

Remove from oven; top with chopped tomatoes and fresh basil.
