Carne Asada Tacos
These flank-steak soft tacos are so tasty and easy, they should be in everyone’s repertoire. Plus they’re made with fresh corn tortillas (not fried) and topped with a quick homemade salsa made with avocado, tomato, onion and a bright squeeze of lime.
Whisk vinegar, chili powder, oil, 2 teaspoons salt and garlic powder in a 9-by-13-inch baking dish. Add steak and turn to coat. Cover and marinate in the refrigerator for at least 1 hour and up to 24 hours.
Make salsa about 20 minutes (and up to 2 hours) before cooking the meat: Gently combine tomatoes, jalapeños (or chiles) to taste, onion, cilantro, avocado, lime juice and the remaining 3/4 teaspoon salt in a medium bowl.
Position rack in upper third of oven; preheat broiler.
Place the steak on a rimmed baking sheet (discard the marinade). Broil 3 to 4 minutes per side for medium. Transfer to a clean cutting board and let rest for 5 minutes. Thinly slice against the grain. Serve the steak wrapped in warm tortillas and topped with the salsa and cheese.
