Gently separate the two sides of each apricot and stuff with the almonds. Wrap each with a segment of the bacon. Arrange in a small nonstick skillet seam-side down. Cook on medium heat until the undersides are well-browned and crisp, 6 to 7 minutes.
Turn the apricots over and continue to cook until browned on the bottom, 2 to 3 minutes more. Add the maple syrup, vinegar and a few grinds of pepper and cook, shaking the skillet to coat, until the liquid has reduced and the apricots are glossy and browned all over, about 1 minute more. Transfer to a small plate and sprinkle with the chives. Serve warm or at room temperature.
