1 c. sour cream
1 c. mayo
1 med. onion, chopped
1/2 stick butter
2 T. chopped fresh parsley
˝ t. Tabasco
dash of Worcestershire and garlic powder

Sauté onion in butter until tender. Mix all together and chill for several hours.
This is quite good served hot also. You can broil it with cheese on top. It's fabulous and makes a great presentation!
