1 tsp chopped green onion
1 1/2 cups soft bread crumbs
1 egg, well beaten
2 tbsp butter, divided
2 lbs halibut fillets
1/2 cup condensed asparagus soup
8 large mushroom caps, fresh or canned
Mix together onions and crumbs. Add egg and 1 tbs melted butter. Spread on fillets, then roll them up and fasten with a tooth-pick.
Place each fillet on a greased square of aluminum foil large enough to wrap completely. Spoon asparagus soup over each fillet. Top with a mushroom cap and a dot of butter. Fold foil around each fillet.
Bake at 400 degrees for 25-30 minutes.
