Instructions
Place 1/2 cup all-purpose flour, 1 teaspoon salt, and 1 teaspoon freshly ground black pepper in a large sealable bag. Close and shake to mix, then add 2 pounds boneless skinless chicken breasts or thighs, cut into large chunks and shake to thoroughly coat.
Heat 2 tablespoons oil in a 12-inch skillet over medium-high heat. Add 1/2 of the chicken in a single layer and cook, flipping it once until it's brown on both sides. Transfer the chicken to a bowl and repeat with the remaining oil and chicken pieces.3 tablespoons olive oil
After removing all the chicken, add 1 small onion, diced to the skillet and cook about 2 minutes, stirring occasionally. Add 3 large garlic cloves, finely minced and cook 30 seconds.
Stir in 1 14-ounce can diced tomatoes, drained and 1 bay leaf and raise the heat to high, then cook 2-3 minutes until the tomatoes begin to break down. Add 2/3 cup good-quality red wine vinegar and boil 30 seconds until the vinegar has almost evaporated.
Place the chicken and any accumulated juices back in the skillet and stir in 1/2 cup chicken stock or broth, 1/2 teaspoon salt, and 1/2 teaspoon pepper. Stir well to combine.
Bring to a boil then reduce to simmer. Partially cover the skillet and cook for 7-8 minutes, stirring occasionally, until the chicken is cooked through. Stir in 1/4 cup chopped fresh parsley and cook for another minute. Remove the bay leaf before serving.
