Serves 4.
4 skinless, boneless chicken breast halves
Salt and pepper to taste
2 tablespoons olive oil
½ onion, diced
1 clove garlic, minced
1/3 cup good quality balsamic vinegar
1 (14.5 ounce) can diced tomatoes
1 teaspoon dried Italian herb blend
2-3 tablespoons fresh chopped basil (optional)
Heat olive oil in a medium skillet. Add onions and garlic, and sauté about 2-3 minutes, or until the onions are starting to get tender and translucent. Season chicken with salt and pepper. Add chicken to the pan and brown on both sides.
Combine tomatoes, balsamic vinegar, and dried seasonings. Season with salt and pepper. Pour over chicken and onions and simmer until chicken is no longer pink and juices run clear, about 15-20 minutes. Add fresh basil and serve.
*If tomato and balsamic mixture is too acidic, add a pinch of sugar while simmering.
