Leftover meatloaf pasta sauce makes weeknight dinners a snap. Sam Zien's recipe reinvents the traditional ground beef and tomato sauce using what you've already got at home.
In a large skillet over medium heat, warm the oil. When hot, add the onion and cook until softened, 3 to 5 minutes.
Add the garlic and cook until fragrant, about 1 minute.
Stir in the meatloaf and mix well to combine.
Squish the tomatoes into the pan by hand, breaking them up well. Add any extra can juices along with the Worcestershire and oregano. Taste, and add sugar, if desired.
Bring to a boil, then lower the heat and let simmer until thickened and the flavors have melded, 20 to 30 minutes.
