Cut chicken breasts in half to form two fairly equally sized pieces. Use a meat mallet to adjust the thickness of each piece as necessary.
In a large bowl, combine honey, mustard, paprika (or cayenne), salt and red pepper flakes. Whisk until combined. Add chicken to bowl, coat well. Cover and chill for at least 2 hours.
Cook bacon until just crispy. Drain and set aside.
Prepare grill or large pan over medium-high heat. Cook chicken on each side for 3-5 minutes. When chicken is nearly done, top off with 2 slices of bacon and a mound of shredded cheese. Cook until chicken is cooked through and cheese is completely melted.
