Place chicken in casserole dish with marinade covering bottom (at very least) to prevent drying.

Bake @ 350° for 35 Minutes

Meanwhile place mushroom slices into separate baking dish covered with Italian dressing. Put into oven about 15 minutes after chicken has been placed into oven.

Once the chicken's 35 minutes is up, place single mushroom slice on top of individual chicken breasts, and cover with a slice of baby swiss cheese. (Use a separate baking sheet, etc.)

If using whole portabellas, (caps) then place chicken on top of caps, then cheese on top of chicken.

Cook additional 5-10 minutes, or just before cheese starts to brown.
