Creating a Tri-Tip Sandwich is straightforward if you follow these easy steps:

1. Prepare the Marinade: In a small bowl, combine olive oil, salt, pepper, garlic powder, onion powder, smoked paprika, cumin, and Worcestershire sauce.
2. Marinate the Tri-Tip: Rub the marinade all over the tri-tip roast, ensuring it’s evenly coated. Place it in a resealable plastic bag or shallow dish and refrigerate for at least 2 hours, preferably overnight.
3. Preheat the Grill: Heat your grill to medium-high heat. If using charcoal, ensure the coals are ready.
4. Cook the Tri-Tip: Remove the tri-tip from the marinade and place it on the grill. Cook for about 5-7 minutes on each side to achieve a nice crust.
5. Check for Doneness: Use a meat thermometer to ensure an internal temperature of 135°F (57°C) for medium rare or 145°F (63°C) for medium, approximately 20-30 minutes.
6. Rest the Meat: Once done, remove the tri-tip from the grill and let it rest for 10-15 minutes for juices to settle.
7. Slice the Meat: Slice the tri-tip against the grain into thin pieces for tenderness.
8. Prepare the Bread: While resting the meat, slice the bread rolls in half and toast them lightly on the grill.
9. Assemble the Sandwiches: Layer slices of tri-tip on the bread rolls. Add your choice of optional toppings.
10. Serve: Press down on the top halves and enjoy your delicious sandwiches!
