Working on a flat work surface, cut a deep pocket into the middle of each chicken breast half, cutting into 1 side and leaving a 1/2-inch margin all around the remaining edges. Divide the cheese and crumbled bacon evenly among the cavities in the chicken breast halves. Season the chicken evenly on both sides with the Essence, salt, and pepper. In a small bowl, combine the honey, mustard, and cayenne and stir well. In a shallow dish combine the cornflakes and pecans and stir well. Brush both sides of each piece of chicken with the honey mixture, then dredge in the cornflake mixture. Place the chicken breasts on the prepared baking sheet and bake for 18 to 20 minutes, or until the chicken is cooked through and juices run clear when pierced with a sharp knife. Serve immediately.
