• 1 tablespoon extra virgin olive oil
  • 1/2 cup finely diced red onion
  • 1 teaspoon minced garlic
  • 1/2 cup chicken broth
  • 1/4 cup tomato sauce
  • 1/4 cup steak sauce
  • 1 tablespoon finely chopped fresh parsley
  • 1 tablespoon Worcestershire sauce
  • 1-1/2 teaspoon ground coffee
  • 1/4 teaspoon freshly ground black pepper


  • 1 tablespoon cracked black pepper
  • 2 teaspoons garlic salt
  • 1 teaspoon dry mustard
  • 1 teaspoon paprika
  • 1/4 teaspoon ground cayenne pepper
  • 1 whole rump, about 1kg
  • 12 slices French bread


  • In a medium saucepan over medium-high heat, warm the olive oil. Add the onion and garlic and cook, stirring occasionally, until soft, about 5 minutes. Add the remaining sauce ingredients. Bring the mixture to a boil, then reduce the heat to a simmer and cook, stirring occasionally, until reduced to 1/2 cup, about 10 minutes. Purée the sauce in a food processor or blender. Allow to cool; cover and refrigerate until ready to use. Bring to room temperature before serving.
  • In a small bowl mix the rub ingredients. Press the mixture into the surface of the tri-tip, cover with plastic wrap, and refrigerate for 3 hours or as long as 24 hours.
  • Allow the tri-tip to stand at room temperature for 20 to 30 minutes before grilling. Follow the grill’s instructions for using wood chips.
  • Sear the tri-tip over direct medium heat (180°C to 230°C), with the lid closed as much as possible, turning once, until both sides are seared, about 5 minutes total. Then continue grilling the tri-tip over indirect medium heat, with the lid closed, until the internal temperature reaches 60ºC, 20 to 30 minutes for medium rare. Allow to rest for 5 minutes before slicing thinly on the diagonal against the grain.
  • Build each sandwich with slices of meat and a dollop of sauce. Serve warm or at room temperature.
