Combine all ingredients, except the reserved 1/2 cup Parmeasean cheese. Place in a casserole dish sprayed with vegetable spray. sprinkle Parmeasean cheese on top  and bake 30 minutes at 325 degrees (or until bubbly).  Serve with cut up vegetables or tortilla chips for dipping.

My family fell in love with this dip that we ordered at Friday's.  I played around with the recipe until I finally hit on the right combinations.  This dip is requested whenever we get together.
