Place sausage in a skillet over medium-high heat. Cook,
stirring constantly until evenly browned. Drain grease, and set aside.
Spread bread pieces in the bottom of a 9x13 inch baking
dish. Drizzle melted butter over the bread pieces, then
sprinkle in the cooked sausage. Cover with shredded cheese. In
a medium bowl, whisk together the eggs, milk, white
wine, Dijon mustard, and green onions. Season with black and
red pepper. Pour the egg mixture over everything in the
baking dish. Cover, and refrigerate overnight.
Remove the dish from the refrigerator 30 minutes prior
to baking to allow it to come to room temperature.
Preheat the oven to 325 degrees F (165 degrees C).
Cover the dish, and bake for 30 minutes in the
preheated oven. Then uncover, and bake for an additional 30
minutes. Remove from the oven, and spread sour cream over the
top. Sprinkle with Parmesan cheese. Return to the oven for
an additional 10 minutes, or until cheese is starting to
brown slightly.
