2 Tb. salted butter
1 cup chopped yellow onion (about 2 medium onions)
* Note: I omit the fresh onion and use dried minced onions*
1 cup fresh bread crumbs - salt them before grinding (2 slices)
1 lb. extra lean ground beef
1/2 lb. ground pork
1 - 8 oz. tomato sauce
2 large eggs
1 cup grated cheddar cheese
1 tsp. salt
1/2 tsp. freshly ground black pepper
2 tsp. dried Italian herb seasoning
Position a rack in the center of the oven and preheat to 350 degrees. In a 10-12 inch cast iron skillet, melt the butter over medium heat. Stir in the chopped onion and cook for 3 minutes. Transfer to a large mixing bowl. Place all of the remaining ingredients in the bowl with the onions and mix together with your hands until well-blended.
Form into a football-shaped loaf in the same skillet in which you cooked the onions. Place the skillet in the oven and bake until the center is no longer pink, about 1 hour. Let cool for 10 minutes. Pour off the excess fat and juices. Slice and serve hot with ketchup for dipping.
