Season the chicken with salt, pepper, and dried basil on both sides.
Heat the oil in a large skillet over medium heat. Cook the chicken for 3-4 minutes per side, or until golden and almost cooked through. Set aside.
Sauté the onion and garlic for 3-4 minutes. Stir in the chicken broth and cook until mostly reduced.
Return the chicken to the pan and add the tomatoes and basil. Cook for 5 minutes or until the thickest part of the chicken reaches 165ºF.
