Form the loaf with an oily hand to avoid sticking.
While the meat is roasting in the oven make the tomato sauce. This can be done beforehand and taken out from the freezer or if in dire needs some ketchup would do it too. Check out how to make: Tomato sauce, BBQ sauce or Bravas sauce. Optionally we can make double of the sauce we can use as a filling and use half of it for brushing. Apply the tomato sauce on top generously.
Place the meatloaf back into the oven. After 30 minutes the meatloaf should be ready. If we aren't happy with the consistency or color of the tomato on top we can roast 10 - 15 minutes more on the highest temperature. This extra roasting will darken and thicken the sauce. It may also burn some spiky bacon a bit.
