Bubble-Up Chicken Enchilada Casserole

"Bubble-Up Chicken Enchilada Casserole is a fun weeknight dinner. The biscuits "bubble-up" during the baking process, which is pretty cool. You can see them popping up throughout the casserole, which consists of shredded chicken, enchilada sauce, black beans, and cheese. Boiling the chicken helps keep the meat moist and makes it easier to shred. This delicious casserole is a great meal during the week. If you want to make it even easier on yourself, cook the chicken a day or two earlier when you have more time on your hands...."
