I sometimes add a decadent handful of crumbled blue cheese to this already decadent dip.
1 cup mayonnaise
1 cup sour cream
Shredded iceberg lettuce, to taste
2 large vine-ripe tomatoes, chopped
1 pound lean bacon, cooked crisp and crumbled
Combine the mayonnaise and sour cream in a small bowl; mix well, and refrigerate until serving time. When ready to serve, toss dressing with the lettuce, tomatoes, bacon and freshly ground black pepper, to taste. Serve with crostini, bagel chips or warm pita bread.
