Season both sides of chicken breasts with salt and pepper.
Heat olive oil in a skillet over medium heat; cook seasoned chicken breasts until chicken is browned, 3 to 4 minutes per side. Add onion; cook and stir until onion is browned, 3 to 4 minutes. (I took chicken breast out as not to overcook)
Pour diced tomatoes (I used canned San Marzano plum tomatos) and balsamic vinegar over chicken; season with basil, oregano, rosemary and thyme (I used fresh). Simmer until chicken is no longer pink and the juices run clear, about 15 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
