Thanksgiving Leftover Casserole
If you love Thanksgiving you’re going to love this casserole. It’s turkey, potatoes, corn and stuffing layered and then drizzled with gravy. If you have leftovers it comes together soooo fast. Even if you don’t have leftovers it’s fairly quick (use instant potatoes, a can of corn, boxed stuffing and a gravy packet). You can also get creative and add in a layer of cranberry sauce, green beans, peas or sweet potatoes.
Serve this alongside more thanksgiving leftovers or some green salad or brussels sprouts. If you have leftovers of leftovers casserole (haha) you can store them in the refrigerator in an airtight container for up to 3 days or you can store them in the freezer for up to 3 months.
