What's for Dinner?

I made this to bring over a friend's house this weekend, and it was a big hit. It's so quick and easy, especially if you buy the lettuce pre-shredded. Makes 25 servings.

INGREDIENTS
1 (8 ounce) package cream cheese, softened
1 (16 ounce) container nonfat sour cream
1 (1.25 ounce) package taco seasoning mix
1/4 head iceberg lettuce - rinsed, dried, and shredded
1 cup shredded Cheddar cheese
3 chopped tomatoes
1 green bell pepper, chopped
1 (2.25 ounce) can black olives, drained

DIRECTIONS
In a medium-sized mixing bowl, combine cream cheese, sour cream and taco seasoning. Spread this mixture in a 9-inch (or a little larger) round serving dish. Top the mixture with lettuce, Cheddar cheese, tomatoes, bell pepper and black olives.
