For Dry Rub:

2½ tsp salt

2½ tsp black pepper

1 tbsp garlic powder

2½ tsp smoked paprika

2 tsp onion powder

1 tsp rosemary, minced

For Tri Tip:

2½ lbs tri-tip roast

1 tbsp extra virgin olive oil

For Basting Marinade:

⅓ cup red wine vinegar

⅓ cup extra virgin olive oil

2 tbsp whole grain mustard

To Assemble:

4 ciabatta rolls, grilled/toasted or roll of choice

1 cup creamy horseradish sauce

1 cup red onions, sliced and lightly caramelized

8 cheese, slices

Dry Rub:

Place all dry rub ingredients into a small mixing bowl and whisk together. Generously sprinkle mixture over the tri tip and rub all over the meat.

Tri Tip:

Tightly wrap tri tip in plastic wrap and refrigerate for at least 3 hours and up to 24 hours.

Unwrap tri tip and gently pat dry. Brush with oil.

Basting Marinade:

Place all basting ingredients into a mixing bowl and whisk together.

Preheat grill to 375 degrees F or place grill pan over medium-high heat and preheat oven to 350 degrees F.

Add tri tip and sear for 3 to 4 minutes. Flip and continue to sear for 3 to 4 minutes.

Lower heat to 350 degrees F and baste roast with basting marinade. Flip and baste other side of the roast, then close grill lid.

Continue to flip and baste tri tip every 8 minutes for about 24 minutes for medium-rare or for 32 minutes for medium.

Remove tri tip from grill or oven and transfer to a cutting board. Allow beef to rest for 6 to 8 minutes.

Thinly slice tri-tip into ¼ to ½-inch pieces.

To Assemble:

Spread tops and bottom of rolls with creamy horseradish sauce. Top bottom rolls with a few slices of tri tip and top each with 2 slices of provolone cheese.

Place sandwiches until a broiler for 1 to 2 minutes, until cheese melts. Top each sandwich with red onions and gently press roll tops over each sandwich. Serve.
