Rub the steak with 1 tbsp oil, chili powder, cumin, garlic powder, 1 tsp salt, and the juice of 1 lime. Let it sit while you slice the peppers and onion into strips.
Heat a large cast-iron skillet over high heat. Sear the steak 4-5 minutes per side for medium; rest 5 minutes on a cutting board.
Add the remaining oil, peppers, and onion to the skillet and cook 6-7 minutes until charred at the edges and tender. Squeeze over the second lime.
Slice the steak thinly against the grain and toss with the veggies.
Serve in warm tortillas with sour cream and guacamole.
