Slow-Cooker Green Chile Chicken Enchilada Pie

In a large bowl, combine the first 7 ingredients. Cut three 30x6-inch strips of heavy-duty foil; crisscross so they resemble spokes of a wheel. Place strips on bottom and up sides of a round 4- or 5-qt. slow cooker. Coat strips with cooking spray. Spread 1/4 cup chicken mixture over bottom of slow cooker. Top with 3 tortillas, overlapping and tearing them to fit, a third of the chicken mixture and a third of the cheese. Repeat twice., Cook, covered, on low until a thermometer reads 165°, about 4 hours. To avoid scorching, rotate slow cooker insert one-half turn midway through cooking, lifting carefully with oven mitts. Turn off slow cooker; let stand, uncovered, 15 minutes before serving. Using foil strips as handles, remove pie to a platter. Cut into wedges. If desired, serve with additional cilantro, salsa, sour cream and lime wedges.
