1 lb. ground ham
1/2 lb. ground beef
1/2 lb. ground lean pork
2 eggs, beaten
1 c. quick cooking oats
1 sm. onion, finely chopped
1 tsp. salt
1/4 tsp. pepper
4 sq. slices Mozzarella, Swiss or American cheese, cut diagonally into 2 triangles each

Mix all ingredients except cheese. Shape mixture into loaf 8x4x3, in ungreased 9x13 pan. Cook uncovered in 350 degree oven until done, 1 - 1 1/4 hours. Remove from oven, let stand a few minutes. Transfer ham loaf to ovenproof platter. Make 8 slits about 1/3 of the way through loaf at 1 inch intervals; place a cheese triangle long side down in each. Place loaf in oven until cheese is slightly melted, 2-3 minutes.
