With iceberg lettuce, Vidalia onions, tomatoes and bacon on sale at Giant Mart this week, here’s a winning recipe to try.INGREDIENTS2 tomatoes (about 8 ounces total), dicedSalt1 small Vidalia onion, mincedWhite wine vinegar, for soaking onion 4 ounces sliced bacon, cut into 1/2 inch pieces2 ounces fresh bread crumbs (about 1/2 cup)Ground black pepper2 ounces mild blue cheese1/2 cup mayonnaise1/2 cup sour cream1/2 cup buttermilk1 tablespoon fresh juice from 1 lemon1 head iceberg lettuce, outer leaves discarded and quartered through core so that each quarter holds togetherMinced chives, for garnishDIRECTIONS1. Set a fine mesh strainer over a bowl and add diced tomatoes. Sprinkle liberally with salt, and toss to combine. In a small bowl, add onion and pour enough vinegar on top to cover. Let tomatoes and onions stand while you prep the other ingredients.2. In a small skillet, cook bacon over medium-high heat, stirring occasionally, until crisped, about 5 minutes. Using a slotted spoon, transfer to a paper towel-lined plate to drain. You should have about 2 tablespoons rendered fat in the skillet. Add bread crumbs and cook over medium heat, stirring frequently, until browned and crisp, 3 to 4 minutes. Transfer to a paper towel-lined plate to drain and season liberally with salt and pepper.3. In a medium bowl, mash blue cheese with a whisk. Whisk in mayonnaise, sour cream, buttermilk, and lemon juice until a smooth, slightly lumpy dressing forms. Season with pepper (the blue cheese will likely make the dressing salty enough, but taste and add salt if necessary).4. Arrange iceberg wedges on plates and spoon dressing on each. Drain quick-pickled onions and sprinkle all over salads, along with drained tomatoes (discard any extracted liquid), bacon, toasted bread crumbs, and chives. Serve.
