This is SO yummy. It's also AMAZING in sandwiches the next day. I think it originally came from Family Fun Magazine, which always has GREAT recipes.
1 ½ lbs lean ground beef
½ lb sweet pork sausage, casings removed
1 cup Cheddar, cut into cubes
2 large eggs
1 medium size onion, finely chopped
½ green pepper, seeded and finely chopped
1 tsp salt
½ tsp pepper
1 tsp celery salt
½ tsp paprika
1 cup milk
1 cup fine dry bread crumbs
Heat the oven to 350. Line a large baking pan with oiled aluminum foil and set it aside. Combine all ingredients in a large mixing bowl. Using your hands, blend everything together until it is evenly mixed. Transfer the meat to the lined baking pan and form it into a long fat loaf, about 10 by 5 inches. Bake the loaf for 60-70 minutes, until the center is cooked. (internal temperature of 160). Serve hot, warm or cold. Makes 8 servings.
