I made this last night and it was wonderful. I did make some changes - I drenched the fish with the dressing and baked for 15 minutes. While it was baking I put the mushrooms in the skillet with butter and garlic and sauteed. When I took the fish out, I poured the mushrooms over the fish and covered each fish completely with the cheese, baked for 2 more minutes. Fabulous, thanks!
