How to Make It
Stir together ground beef and next 11 ingredients in a large bowl just until combined. Shape mixture into 12 (2- x 4-inch) loaves, and arrange on a rack in an aluminum foil-lined broiler pan.
Pour half of tomato sauce evenly over each loaf, and arrange 2 bacon slices over each loaf.
Bake at 350° for 40 to 45 minutes. Let stand 10 minutes before serving.
To make ahead: Omit tomato sauce and bacon. Wrap unbaked meat loaves in plastic wrap and foil. Freeze up to 1 month. Thaw in refrigerator overnight, unwrap, and proceed as directed.
