Preheat your oven to 375°F.
Place the remaining oil in a frying pan, heat and sear chicken on both sides.
Put the chicken in an oven safe pan and brush liberally with the marinade.
In the same frying pan and add the butter and sauté the mushrooms.
Season chicken breasts with salt and pepper.
Place bacon strips across each breast, spoon mushrooms on top, and then add approximately 1/3 to 1/2 of a cup of cheese on each backspace.
Cover the pan with aluminum foil and bake 7 to 10 minutes or until the cheese is melted and bubbly. Sprinkle with parsley and serve with honey mustard marinade.
