Matambre literally means "Hunger Killer"
This a South American (Brazil/Argentina) stuffed roast that sounds more difficult to make that it is. It takes about 20 minutes to assemble. It's meant to be cooked on a grill, but can also be cooked in your even. Either way, its succulent and delicious.

  3. Marinade the meat in the refrigerator for 4-6 hours, turning once or twice while marinading.
  4. Set up the grill for indirect cooking or PREHEAT OVEN TO 325.
  5. On a large sheet of heavy duty foil, arrange bacon strips, leaving 1 " between each.
    (Strips should run parallel to bottom edge of cutting board.)
  6. Generously rub all sides of the meat with Olive Oil then season with salt & pepper to taste. Sprinkle with remaining Oregano & Sage.
  7. Place flank steak on top of Bacon, so grain of meat runs perpendicular to bacon.
  8. Use some of the strips of Sausage to make a single neat row, end to end, along edge of meat closest to you.
  9. Place row of Red Pepper strips next to it.
  10. Next, make a row of Cheese strips, then a row of Carrot, then Spinach, then Onion, Green Pepper, then eggs.
