Chicken Taco Casserole

"Learn how to make this delicious chicken taco casserole with crispy fried tortilla strips, corn, black beans, and tomatoes in a creamy, cheesy base, topped with avocado and chopped fresh cilantro. This is a fun and delicious meal. It is one that my family goes nuts over. You can’t go wrong with a classic like this! As a busy evening shortcut, use diced rotisserie chicken tossed with taco seasoning. You can prepare the tortilla strips up to a day in advance. Most grocery stores sell ready-made tortilla strips, but I think they taste better fresh. To prevent premature browning, brush the diced avocado with lemon or lime juice. This casserole is best served promptly while the tortilla chips are crunchy and the avocado is a handsome shade of green."
