Frisee Salad with Eggs

Place salad greens in a large bowl and set aside. In a heavy pan over medium heat, cook bacon in olive oil until browned and crisp, stirring frequently, about 4 minutes. Add onions and cook until crisp tender, about 2 minutes. Add vinegar, then raise heat, and simmer for 1 minute. Season with salt and pepper and set aside.

In another small heavy skillet, melt butter and cook eggs, one at a time, until desired doneness. Unless you are using pasteurized eggs, for safety's sake cook the eggs well done. I like mine over hard.

Pour the warm dressing over greens in bowl and top with the eggs. Serve immediately.
