Tri-Tip

  • 2-3 lbs tri-tip roast Santa Maria-style cut
  • 1 tbsp salt
  • 1 tbsp black pepper
  • 1 tbsp garlic powder
  • 1 tsp smoked paprika optional

Sandwich Components

  • 4 ciabatta or French rolls toasted

Instructions
 

  • Pat the tri-tip dry and season generously with salt, black pepper, garlic powder, and smoked paprika.

  • Slice the tri-tip against the grain in ¼-inch thick slices.
  • Heat olive oil in a skillet over medium heat and sauté onions for 7-10 minutes until caramelized.
  • Spread butter on the cut side of ciabatta rolls and toast until golden brown.
  • Place pepper jack cheese on the warm bread so it melts slightly.
