Tip: It can be hard to find individual chicken breasts small enough for our recommended 4-ounce (uncooked) portion size. If yours are closer to 5 ounces each, remove the tender (about 1 ounce) from the underside to get the correct portion size. Wrap and freeze the leftover tenders; when you have gathered enough, use them in a stir-fry, for chicken fingers or in soups.
Note: Chipotle peppers are dried, smoked jalapeño peppers. Ground chipotle can be found in the specialty spice section of most supermarkets.
