Ingredients

4 ounces slab bacon, cut into 1-by-1/4-inch strips

3 tablespoons white-wine vinegar

12 ounces frisee, torn into pieces

Coarse salt and ground pepper

Preparation

In a medium skillet, cook bacon over medium, tossing occasionally, until browned, 6 to 8 minutes. With a slotted spoon, transfer to a paper-towel-lined plate to drain. Set bacon aside.

Pour off all but 2 tablespoons fat from skillet; return skillet to heat. Add vinegar; stir, scraping up browned bits until dressing is combined.

In a large bowl, toss frisee with warm dressing. Add bacon, and season with salt and pepper. Serve immediately.
