White cheddar cheese makes this a rich, creamy, yet spicy dish with the grilled sliced chipolte chicken. And topped with a cilantro sour cream. I love all in one menus. Add a fresh "veggie" of your choice like corn on the cob or green beans, or maybe a nice green salad and you have a great dinner. As the chicken marinates all day, the dip can be made way ahead as well and polenta takes just a few minutes while the chicken grills. Just a little planning and you have a great dinner
