Fiesta Chicken Casserole

We are entering the season of pumpkin spice, apple cider, slow cookers, and hearty casseroles. I love fall. Big fluffy sweatshirts, cool nights, and warming comfort foods are everywhere. Yes, I do get the blues in the fall but there is so much I love about it too.

This casserole is a simple dish that makes great use of leftover chicken. I always cook extra chicken breasts to have “leftovers.” They make simple casseroles and salads for quick weekday meals. Best tip I can give you is to always cook extra meat when you are cooking and plan ahead on how to use it.

Verdict: You can spice this casserole up – use more Cayenne and Chili Powder or cool it down. It is entirely up to you! Make it the night before or in the morning to pop in the oven after work or school.

We served this with a green side salad to complete the meal.
