Tex-Mex Dip

Peel, pit and mash the avocados with lemon juice, salt and pepper; set aside.

Combine the sour cream, mayonnaise and taco seasoning.

For best effect, use a glass bowl with straight sides. To assemble: spread the bean dip over the bottom of bowl.

Over that, layer the avocado mixture, over that the sour cream mixture. Sprinkle the tomato, black olives and scallions over the top and cover with shredded cheese.

Serve chilled or at room temperature with tortilla chips.
