Instructions
In a large bowl, whisk the lime juice, minced garlic, cumin, chili powder, oregano, 3 tbsp vegetable oil, 1.25 tsp kosher salt, and black pepper.
Add the skirt steak and turn to coat well. Cover and marinate in the refrigerator for 30 minutes to 2 hours.
Thinly slice the onion and bell peppers and set aside.
Heat a large cast-iron skillet over high heat until very hot, 3β5 minutes. Add 1 tbsp vegetable oil and swirl to coat.
Remove the steak from the marinade, letting excess drip off. Sear until well browned, 3β5 minutes per side, to medium-rare (internal 125β130Β°F). Transfer to a cutting board and rest 5β10 minutes.
In the same skillet, add the sliced onion and bell peppers with 0.5 tsp kosher salt. Cook over high heat, stirring occasionally, until tender-crisp and charred in spots, 5β7 minutes. Scrape up any browned bits.
Slice the rested steak across the grain into 0.5-inch strips. Return the steak to the skillet with the vegetables and toss over heat for 30β60 seconds to warm through. Taste and adjust seasoning.
Warm the flour tortillas: wrap in foil and heat in a 350Β°F oven for 5β10 minutes, or char in a dry skillet over medium-high heat, 30β45 seconds per side, until pliable.
Serve the steak and peppers hot with warm tortillas, salsa, cilantro leaves, and lime wedges.
