Season the chicken breasts with the 1 tsp. salt and 1/2 tsp. pepper. In a large saucepan over medium heat, warm the olive oil. Add the chicken, and cook until browned, about 5 minutes. Transfer the chicken to a plate. Add the garlic and chili and sauté until fragrant, about 1 minute. Add the broth, water, lime juice and oregano, then return the chicken to the pan.
