OLD-FASHIONED TUNA-OLIVE-MACARONI LOAF

Steps:

• Preheat the oven to 350 degrees.
• Line a standard-size loaf pan with aluminum foil.
• Spray the foil-lined pan with non-stick cooking spray and set it aside.
• Cook the macaroni in a large pot of boiling water according to package directions.
• Drain it thoroughly and add the butter, stirring until it melts, set aside.
• Combine the eggs and egg whites in a large bowl and beat them lightly.
• Add the onion, tuna, olives and bread crumbs and mix well.
• In a large saucepan combine the milk, salt, dry mustard and horseradish.
• Mix well and bring to a boil over medium heat.
• Reduce the heat to low and simmer for 2 minutes.
• Add the cheese and stir just until it starts to melt, then pour it into the tuna mixture in the bowl.
• Add the macaroni and mix well.
• Carefully spoon the mixture into the prepared pan and, using your hands, press it down firmly.
• Bake in the preheated oven until golden brown, about 1 hour.
• Allow to cool for 10 minutes before turning it over onto a serving dish or cutting board.
• Using a serrated knife, cut the loaf into 8 slices.
