Ingredients

  • 4 (6 ounce) boneless skinless chicken breast halves
  • 1/2 teaspoon kosher salt, divided
  • 1/2 teaspoon ground black pepper, divided
  • 1/4 cup parmesan cheese, grated
  • 1 tablespoon all-purpose flour
  • 2 teaspoons olive oil, divided

  • 1/4 cup chicken broth
  • 1 tablespoon sherry wine vinegar
  • 2 cups cherry tomatoes, quartered

Method

  • Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/2 inch thickness using a meat mallet or a small heavy skillet.
  • Sprinkle chicken with 1/4 teaspoons salt and 1/4 teaspoons pepper.
  • Combine cheese and flour in a shallow dish. Dredge one side of each chicken breast in the cheese mixture.
  • Heat 1 teaspoons oil in a large nonstick skillet over medium-high heat. Add 2 chicken breast halves, cheese side down; cook 4 minutes on each side or until done. Repeat procedure with remaining oil and chicken breast halves.
  • Remove from pan; keep warm.
  • Carefully wipe any browned bits from the pan using a paper towel.
  • Coat pan with cooking spray. Add onion; saute 2 minutes. Stir in broth and vinegar; cook 1 minute or until liquid almost evaporates. Add tomatoes, remaining salt and pepper, and oregano; cook 2 minutes.
