To Make Stuffing: Brown sausage in a large
skillet over medium high heat; once sausage starts to brown, add mushrooms and
saute for 5 minutes, then add green onion and garlic and saute for another 2
minutes. Remove stuffing mixture from heat, put in a food processor and add 1
tablespoon salad dressing. Process slowly in processor, roughly chopping.
Preheat oven to 375 degrees F (190 degrees C).
Cut 2 inch slits in sides of chicken breasts and
stuff with as much stuffing as breast will hold. Season both sides of breasts
liberally with Cajun-style seasoning and sear in a hot skillet for 1 to 2
minutes per side, then place in a lightly greased 9×13 inch baking dish. Top
with leftover stuffing and remaining 3 tablespoons salad dressing.
Bake at 375 degrees F (175 degrees C) for 30
minutes or until chicken is cooked through and juices run clear.
