you will need these ingredients in the following quantities :

2 teaspoons olive oil
4 ounces pancetta, cut into 1/4-inch pieces
2/3 cup buttermilk
1/2 cup sour cream
1 large garlic cloves or 2 small, minced
6 ounces crumbled Gorgonzola
Salt and freshly ground black pepper
1 head iceberg lettuce, cut into 6 wedges

Cooking Recipe:

Heat the oil in a heavy medium skillet over medium heat. Add the pancetta and saute until crisp and golden, about 5 minutes. Using a slotted spoon, transfer the pancetta to a paper towel-lined plate to drain (the part where it exits) the excess oil.

Stir the buttermilk, sour cream, and garlic in a medium bowl to blend; mix 2/3 of the cheese. Season the dressing with salt and pepper, to taste.

(The dressing can be made up to 2 days ahead. Cover and refrigerate. Stir to blend before using, adding more milk to thin the sauce, if necessary.)

Arrange each of 6 lettuce wedges on 6 plates. Spoon the dressing over the lettuce. Sprinkle with the pancetta and remaining cheese and serve.
