In a bowl, combine the mustard, honey, 1-1/2 teaspoons oil and lemon juice. Pour 1/2 cup into a large resealable plastic bag; add the chicken. Seal the bag and turn to coat; refrigerate for 2 hours. Cover and refrigerate the remaining marinade.

Drain and discard marinade from chicken. In a large skillet over medium heat, brown chicken in remaining oil on all sides. Sprinkle with salt, pepper and paprika. Transfer to a greased 11-in. x 7-in. x 2-in. baking dish.

In the same skillet, saute mushrooms in butter until tender. Spoon reserved marinade over chicken. Top with cheeses and mushrooms. Place bacon strips in a crisscross pattern over chicken.

Bake, uncovered, at 375? for 20-25 minutes or until a meat thermometer reads 170?. Sprinkle with parsley.
