When you think of casserole, low carb probably doesnt come to mind thanks to the ubiquitous potatoes or rice or pasta. But a delicious casserole doesnt have to be synonymous with starchy comfort and this chicken fajita casserole proves it once and for all. Comforting in its creaminess and cheesiness instead, its a quick dinner to throw together but its the kind that doesnt taste like an afterthought. Its so zesty and full of flavor that it never disappoints.
