head of leaf or boston lettuce
medium onion, thinly sliced
In a large skillet, over medium heat, fry bacon slices until crisp.
Drain and discard all but 1/4 cup of the bacon drippings; return the drippings to the skillet.
Meanwhile, into a salad bowl, tear lettuce into bite-sized pieces.
Crumble bacon and add to lettuce with the onion slices, tossing until well mixed.
Stir the remaining ingredients into bacon drippings and heat to boiling, stirring constantly.
Remove from heat and pour over lettuce mixture, tossing until lettuce is slightly wilted and coated with dressing.
