Preheat smoker to 250 degrees Fahrenheit using oak or fruit wood like apple or cherry.
Coat roast in olive oil and season the roast with the beef seasoning.
Place the seasoned tri tip in the smoker and smoke for 45 minutes to one hour. We like rare to medium rare and target 125 to 130 degrees Fahrenheit using a good instant read thermometer.
Remove from smoker and let rest 10 minutes. Then slice thinly against the grains.
Tri Tip Sandwiches
Start by toasting the sliced bread. Preheat flat griddle or large skillet to medium heat. Apply one side of the bread with olive oil or butter and place that side on the hot pan. Move around the pan gently for 2 minutes or until it is lightly toasted.
Coat the non toasted side with a layer of the chimichurri, then add the sliced tri-tip. Top with onions, arugula, and hot pickled peppers and add the top of the sandwich bread. Cut and serve.
Notes
Note: The chimichurri adds a lot of flavor, the red onion and arugula add additional texture and some heat. Gas Grill: We recommend you grill if using gas. Set one burner to medium-high heat. Grill the tri tip direct over the flame for 5 minutes (or until you see a nice crust) and then flip and continue to grill direct an additional 5 minutes. Then move to the side with no flame (indirect) and cook until it reaches your desired internal temperature.Alternatively you can use our guide on how to smoke on a gas grill for this recipe.
