"Chicken Pot Pie Pierogi Casserole - comfort food at its best! All you need is a few biscuits and dinner is done! Can make ahead of time and refrigerate or freeze for later. Pierogis, cream of chicken soup, sour cream, mixed vegetables, cheddar cheese, chicken, garlic, onion, salt and pepper. Everyone LOVES this easy casserole. Even our picky eaters cleaned their plate. #casserole #chicken #chickenpotpie..."
