Prepare the Chicken: Season the chicken breasts with garlic powder, onion powder, salt, and pepper. Heat olive oil in a skillet over medium heat and sear the chicken on both sides until golden brown, about 6-8 minutes per side, or until fully cooked (internal temperature of 165°F).
Prepare Honey Mustard Sauce: In a small bowl, whisk together honey, Dijon mustard, and mayonnaise until smooth. Set aside.
Layer the Chicken: Place the cooked chicken breasts on a baking sheet. Spread a generous layer of the honey mustard sauce on each chicken breast, then top with 2 slices of crispy bacon.
Add the Cheese: Sprinkle shredded cheddar cheese evenly over each piece of chicken and bacon.
Bake: Preheat your oven to 375°F. Bake the chicken in the oven for 5-7 minutes, or until the cheese is melted and bubbly.
Remove from the oven and sprinkle with fresh parsley if desired, then serve hot.
