Instructions: 1. Heat oven to 425 degrees F. Grease a shallow 9-inch casserole. (If using fresh tuna, cut tuna steaks into sticks about 1/2" thick and 2" long. Toss with lemon juice and refrigerate.)

2. Start cooking noodles according to package directions. Meanwhile, melt 1 tablespoon butter in large skillet over medium heat. Add mushrooms and cook without stirring, 1 to 2 minutes, until browned. Stir and add 1 tablespoon water; cook 1 minute until tender.

3. Melt remaining butter in medium saucepan over medium heat. Stir in flour and cook, stirring, 1 minute. Stir in milk and bring to simmer, stirring constantly. Stir together cornstarch, clam juice, and wine. Pour into sauce, stirring constantly; add salt, pepper, and nutmeg. Simmer 2 to 3 minutes until thickened.

4. Combine noodles with sauce, tuna, and mushrooms. Add dill and transfer to casserole; top with bread crumbs. Bake 20 minutes until bubbly. Let stand 10 minutes before serving.

To reheat: If room temperature, bake 20 minutes at 350 degrees F; if cold, 30 minutes.
