Brown the ground beef in a large pan. Drain the fat and add the taco sauce. Mix well and set aside.

In a bowl, beat the cream cheese until smooth. Add the sour cream and taco seasoning. Mix until well combined.

In a 3 quart dish, begin layering in this order - refried beans, cream cheese/sour cream mixture, ground beef, cheddar cheese, lettuce, tomatoes, black olives and green onions.

Chill for 30 minutes prior to serving.
