In a small bowl, combine the bay leaves, salt, cayenne pepper, ground black pepper, ground white pepper, cumin, and nutmeg. Set aside.

Melt butter in a saucepan over medium heat. Add onion, bell pepper, green onions, garlic, hot pepper sauce, Worcestershire sauce, and reserved seasoning mix. Saute until the mixture sticks to the bottom of the pan, about 6 minutes. Stir in milk and ketchup, cooking for 2 more minutes.

Remove vegetable mixture from heat and let cool to room temperature. In an ungreased 9x13 inch baking dish, combine beef, sausage, eggs, the vegetable mixture, and bread crumbs. Remove bay leaves. Mix by hand and form a loaf about 1½ inches high.
