Tools & Equipment
Ingredients

- 3 cloves - Garlic: Minced.
- 1 tsp - Cumin & 1 tsp Smoked Paprika: For that classic smoky depth.

- 1 - Large White Onion: Sliced into half-moons.

Instructions
Marinate the Beef
Step 1
In a gallon-sized Ziploc bag or glass bowl, whisk together the olive oil, soy sauce, lime juice, garlic, and spices. Add the skirt steak, ensuring it's fully coated. Let it marinate in the fridge for at least 2 hours (but no more than 8, or the lime juice will break down the meat texture too much).
Prep the surface
Step 2
Preheat your flat top griddle to high heat (about 450°F). You want the surface screaming hot to get a char without overcooking the center.
Sear the Steak
Step 3
Remove the steak from the marinade and pat it dry with paper towels (moisture is the enemy of a good sear). Lightly oil the griddle. Lay the steak down; it should sizzle loudly. Cook for 3–4 minutes per side until the internal temperature reaches $130^\circ F$ to $135^\circ F$ for Medium-Rare.
Sauté the Veggies
Step 4
While the steak is resting, add a bit more oil to the other side of the flat top. Toss on the onions and peppers. Use your spatulas to keep them moving. Cook for 5–7 minutes until the edges are charred but the veggies still have a slight "snap."
Toast the Tortillas
Step 5
Clear a spot on the griddle and lay down your tortillas for about 30 seconds per side until they are warm and slightly charred.
Assemble and Serve
Step 6
You might be tempted to use Flank steak, but Skirt steak has a higher fat content and a looser grain structure, which means it soaks up marinades better and offers a much "beefier" flavor when seared at high temperatures.
