Broiled Steak Sandwiches With Balsamic Vegetables

• 1 pound strip steak
• Kosher salt and pepper
• 4 Roma (plum) tomatoes, halved
• 1 medium red onion, sliced into 1/4-inch-thick rings
• 4 teaspoons olive oil
• 1 tablespoon balsamic vinegar
• 4 pieces focaccia or French bread, cut in half
• 3 ounces blue cheese

1. Heat broiler.
2. Season the steak with 1/2 teaspoon salt and 1/2 teaspoon pepper. Line a rimmed baking sheet with foil. Place the steak on one half of the baking sheet.
3. Toss the tomatoes and onion in a medium bowl with the oil, vinegar, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Place the onion and tomatoes, cut-side down, on the other half of the baking sheet.
4. Broil the steak and vegetables, turning everything once, until the steak reaches the desired doneness, 4 minutes per side for medium rare. Remove the steak and return the vegetables to oven until browned, about 1 minute more.
5. Slice the steak. Place the bottom halves of the bread cut-side up and top with the steak, onions, tomatoes, and cheese. Sandwich with the remaining bread. Serve warm.
6. If blue cheese is too strong for your taste, try topping this sandwich with a creamy goat cheese. Or play off the tartness of the balsamic vinegar with slivers of salty Parmesan or Manchego.
