1. Pound chicken to 1/4-in. thickness; cut each half into three pieces. Season with salt, pepper and lemon-pepper. In a large skillet, saute a third of the chicken at a time in butter until browned and no longer pink. Remove and keep warm.
2. In the same skillet, saute onions until tender. Add the cream, lemon juice and tarragon; bring to a boil. Cook and stir 5-6 minutes or until thickened. Serve with chicken and rice. Yield: 4 servings.
