Preheat oven to 350 degrees. Place an oven proof rack inside a rimmed baking sheet and spray with nonstick spray. Cut chicken breasts into one inch cubes and place them in a large bowl. Warm apricot pepper jam in a microwave safe bowl for 30 seconds. Reserve two tablespoons, and then pour the rest over the chicken and toss to coat. Wrap each chicken cube with a half strip of bacon, and secure with a toothpick. Brush each one with the reserved jam. Bake for 20 minutes, then flip each chicken bite over. Bake for an additional 20-25 minutes or until the bacon is nicely browned. In a small microwave safe bowl, combine jam and water. Heat for 30 seconds and stir. If it is still to thick, add another tablespoon of water and reheat.
