2 tablespoons canola oil
1/2 teaspoon salt, divided
1 beef top sirloin steak (1-1/2 pounds)
1/4 cup soy sauce

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., 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.
