Barbecued Flank Steak Sandwiches

• Cooking spray
• 1 (1-pound) flank steak, trimmed
• 1/2 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 4 (1/4-inch-thick) slices red onion
• 1/4 cup ketchup
• 2 tablespoons light brown sugar
• 1 tablespoon cider vinegar
• 1 tablespoon Worcestershire sauce
• 1/4 teaspoon chipotle chile powder
• 4 (3-ounce) hoagie rolls, split

1. Heat a grill pan over medium-high heat. Coat pan with cooking spray. Sprinkle steak evenly with salt and pepper. Add steak to pan; cook 6 minutes on each side or until desired degree of doneness. Remove steak from pan; let stand 10 minutes. Add onion to pan; cook 3 minutes on each side or until lightly browned. Remove from pan; cool.
2. Combine ketchup and next 4 ingredients (through chipotle chile powder) in a large microwave-safe bowl, stirring well. Microwave at HIGH 1 minute or until thoroughly heated. Cut steak diagonally across grain into thin slices. Add steak to ketchup mixture; toss to coat. Divide steak mixture evenly among bottom halves of rolls; top each serving with one onion slice. Place top half of roll on each sandwich.
