In a bowl, combine the steak fillets with minced garlic, lime juice, olive oil, cumin, oregano, paprika, onion powder, garlic powder, and salt. Toss until the steak is well coated. Cover and refrigerate for at least 2 hours to let the flavors soak in.
1 pound steak, 1 tablespoon olive oil, 3 cloves garlic, 1 lime, 2 teaspoons ground cumin, 1½ teaspoons dried oregano, ½ teaspoon paprika, ½ teaspoon onion powder, ½ teaspoon garlic powder, 1 teaspoon salt
While the steak marinates, place sliced red onions in a jar or bowl. Pour in the apple cider vinegar, honey, and salt. Stir well and let sit for at least 30 minutes at room temperature (or refrigerate longer for a deeper tangy-sweet flavor).
1 medium red onion, ½ cup apple cider vinegar, 2 tablespoons honey, ½ teaspoon salt
Heat a skillet or grill pan over medium-high heat. Sear the marinated steak for about 4 minutes per side, or until desired doneness. Let the steak rest for a few minutes before slicing thinly against the grain.
Heat the flour tortillas in a dry pan or over an open flame until warm and lightly charred.
