Start by spreading the 20 ounces of Frito Lay bean dip evenly across the bottom of your 9x13 inch dish.
Next, take your creamy guacamole and spread it over the bean dip layer.
In a large mixing bowl, combine the 2 cups of sour cream with the taco seasoning mix. Stir until smooth and well blended.
Carefully spread the seasoned sour cream mixture over the guacamole layer.
Sprinkle the chopped green onions evenly over the sour cream layer, followed by the seeded chopped tomatoes and sliced black olives.
Finally, top your dip with a generous layer of shredded Cheddar cheese.
Cover your dip with plastic wrap and chill it in the refrigerator for at least 30 minutes before serving.
