Slow cooking the chicken breasts on the stovetop in a flavorful simmer sauce made of diced tomatoes, chipotle peppers, and cumin makes for juicy, fork-tender chicken. A single chipotle gives this dish a little bit of heat, but use two or even three if you prefer things spicier. This recipe’s large yield makes it perfect for serving a crowd at your next fiesta or a great make-ahead item for planned leftovers because it will also freeze well. Make tacos and serve the succulent chicken spooned into warm tortillas or crisp lettuce leaves. Or make a taco bowl and serve it over a bed of lettuce, tomatoes, and a scoop of brown rice.
