In a small bowl, mix together olive oil, garlic powder, smoked paprika, salt, and pepper. Rub this mixture evenly over the chicken breasts.
Heat a large oven-safe skillet over medium heat and add the chicken breasts. Sear each side for about 5 minutes, until golden brown.
While the chicken is cooking, sauté the mushrooms in the same skillet until they soften (about 4-5 minutes). Remove and set aside.
Once the chicken is browned, brush a generous amount of honey mustard dressing over each breast.
Layer the sautéed mushrooms on top of the honey mustard chicken, followed by the crumbled turkey bacon.
Sprinkle the shredded Monterey Jack and cheddar cheeses evenly over the top of the chicken.
Transfer the skillet to the oven and bake for about 15-20 minutes, or until the chicken is fully cooked (internal temperature of 165°F or 74°C) and the cheese is melted and bubbly.
Once cooked, remove from the oven and let it rest for 5 minutes.
Garnish with freshly chopped parsley before serving.
Notes
Serve the chicken on a bed of mixed greens, drizzled with additional honey mustard dressing for extra flavor.
