Place bacon in medium nonstick skillet; set over medium heat. Cook, stirring occasionally, until crisp, 2-3 minutes. With slotted spoon, transfer bacon to plate lined with paper towels and drain. Pour off and discard all but 1/2 tsp of bacon drippings.
Sprinkle chicken with paprika, pepper and salt. Add chicken to same skillet and cook, turning once, until cooked through, about 8 minutes. Transfer the chicken to plate.
To make vinaigrette, add scallions to same skillet; cook, stirring constantly until softened, 1 minute. Add broth and vinegar; bring to boil. Cook, stirring constantly, until liquid is reduced by half, about 1 minute. Stir in bacon. Spoon Vinaigrette over chicken.
Note: White balsamic vinegar is a lighter, sweeter cousin of the more common dark balsamic vinegar. If you don't have any on hand, use white wine vinegar in this recipe.
