Beef Tenderloin Steaks with Balsamic Green Beans

Ingredients

• 2 teaspoons extra-virgin olive oil, divided
• 1 cup thinly sliced yellow onion
• 1 cup thinly sliced red onion
• 1/4 cup sliced shallots
• 3 garlic cloves, minced
• 1/2 cup low-sodium beef broth
• 2 cups green beans, trimmed
• 2 tablespoons balsamic vinegar
• 4 beef tenderloin steaks (4 oz each), trimmed of visible fat, or 1 lb flank steak
• 1/4 teaspoon black pepper
• Cooking spray

Steps

1. Heat 1 teaspoon of the oil in a medium saucepan over medium-high heat. Cook the onions and shallots 6 minutes, then the garlic 1 minute.
2. Add the broth and cook 4 minutes, until the onions are tender and the liquid is almost gone.
3. Add the green beans and vinegar, cover, and cook 4 minutes, until crisp-tender. Stir in the remaining teaspoon of oil and keep warm.
4. Season the steaks with pepper. Heat a cast-iron skillet over medium-high heat and coat with cooking spray. Cook the steaks 3 minutes per side, or to the doneness you like.
5. Let the steaks rest 5 minutes, then serve with the green beans.
