Impossibly Easy Cheeseburger Pie

Our wonderful friend Julia not only coordinated meals for us right after Abby was born, but she also brought us this dish. I had seen this recipe before but hadn't made it. I definitely recommend it if you are looking for something quick and child-friendly. My picky eaters liked it.
