Cheesy Tortellini and Pesto Chicken Casserole

"One of the things that I really enjoy as a food blogger is that it forces me to continually try new things and introduce different foods to my family. We're well acquainted with casseroles, of course, but I've never thought to use tortellini in one before! We love casseroles because they're so convenient. You can make them up ahead of time, refrigerate or freeze them, and have a delicious filling dinner ready when you want it in no time at all. This Cheesy Tortellini & Pesto Chicken Casserole recipe was a huge hit with our family and one we will definitely be adding to the regular rotation."
