Everyone loves the tangy sauce that goes with these sizzling steak tacos. For an authentic feel, I like to wrap the tortillas in foil and steam them while the steak and onions are cooking. —Lois Szydlowski, Tampa, Florida


  • 2 medium red onions, cut into 1/4-inch slices
  • 2 tablespoons canola oil
  • 1/2 teaspoon salt, divided
  • 1 beef top sirloin steak (1-1/2 pounds)
  • 1/4 cup soy sauce
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon brown sugar
  • 1 tablespoon balsamic vinegar
  • 1 garlic clove, minced
  • 1/4 teaspoon pepper
  • 12 flour tortillas (6 inches), warmed
  • 1 cup crumbled blue cheese


  1. Brush onion slices with oil; sprinkle with 1/4 teaspoon salt. Sprinkle steak with remaining 1/4 teaspoon salt. Grill onions and steak, covered, over medium heat until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°), and onions are tender, 4-6 minutes per side. Let steak and onions stand 5 minutes.
  2. Meanwhile, in a large bowl, combine soy sauce, Worcestershire, brown sugar, vinegar, garlic and pepper. Halve onion slices; cut steak thinly across grain. Add onions and steak to soy mixture; toss to coat. Serve in tortillas with blue cheese.
