3 Tablespoons olive oil
2 medium onions, sliced into 1/2-inch-thick rings
Salt
Pepper
4 minute steaks (3 ounces each)
2 tablespoons worcestershire sauce
Toasted country bread

Heat 2 tablespoons of the olive oil in a large skillet over medium-high heat (oil is in with the onions); cook the onions until browned, tossing occasionally, 10 to 15 minutes. Season with salt and pepper; remove.

Heat the remaining tablespoon of olive oil (in a bag) in the same skillet over high heat. Season the steaks with salt and pepper. Cook for 30 seconds on each side; remove. Add the worcestershire sauce and 2 tablespoons water to the skillet (worcestershire and water have already been combined), scraping up the browned bits with a wooden spoon. Return the onions to the skillet; toss.

Sandwich the steak, onions and cheese between toasted bread. Serve immediately.
