Preheat oven to 425 degrees F. Heat oil in a large, oven-safe skillet over medium-high heat.

In a small bowl, combine chili powder, cumin, coriander, salt, onion powder and pepper. Rub mixture into the meat on all sides.

Once oil is hot, place tri tip fat-side down in the pan. Sear the meat by cooking for 3-4 minutes on each side until browned.

Place skillet in preheated oven and cook for 20-25 minutes, or until the internal temperature reaches at least 135 degrees F.

Remove from oven and let rest for 10 minutes. Transfer to a cutting board then slice or dice tri tip.

Serve tri tip on top of tortillas (33 grams of cooked tri tip per tortilla) and top with desired toppings.
